Reusable Rounds and Tissues Undercut What They Replace

TL;DR — Two of the reusables in our 31 August 2026 US price survey come out cheaper per use than every disposable we could price in their own category. A LastRound Refill works out at $0.0051 a use and the LastRound set at $0.0091. The ten confirmed disposable cotton rounds run $0.0200 to $0.0624 each, with a median of $0.0239. A LastTissue set works out at $0.0077 a tissue, against seven confirmed disposable tissues at $0.0103 to $0.0497. Both results rest on lifetime figures claimed by the manufacturer — 250 washes per round, 3,100 tissues per set. The manufacturer is us. We have not tested either, and they are labelled as claims everywhere they appear. On waste the answer is a count rather than a cost: one object kept and washed, against 1,750 pads and 3,100 tissues never bought.

All prices in this article were read at the named US retailers on 31 August 2026 and change without notice.

"Reusable is cheaper" is the claim this product category leans on, ours included. The honest version of it is narrow. A reusable pays for itself when the disposable it replaces is expensive enough per unit, and when the reusable genuinely lasts. Two swaps let us price both halves of that sentence from one day's reading — cotton rounds and facial tissues. This article shows the arithmetic in full, including the assumption each result depends on.

Method

Prices were read at Target.com, Walmart.com, Amazon.com, Walgreens.com, Ulta.com and lastobject.com on 31 August 2026. Each one was read directly on the retailer's own product page. We took list prices, not member or promotional prices, and used no price aggregators. Every row carries a URL and a verbatim price quote from the fetched page. As a spot check, the three most expensive rows plus one random row per category were re-fetched and re-verified the same day. All four matched within $0.00. CVS.com is geo-blocked outside the United States and could not be read at all. Rows whose price could not be confirmed word-for-word on the page were excluded (more under What we could not price).

Per-unit prices were computed from pack price divided by stated pack count before any writing happened. For a reusable, cost per use is the purchase price divided by the manufacturer's claimed lifetime. That lifetime is a claim, not a measurement. It is flagged as such in every table it touches.

What "pays for itself" means here

Two questions, kept apart, because blending them would let us hide whichever one went badly:

1. Cost per use = price ÷ uses. For a disposable, one unit is one use. For a reusable, uses come from the maker's stated lifetime.
2. Units discarded — pieces that leave the bathroom for the bin, counted in units because no product page we opened publishes a per-unit weight.

A reusable that wins on the first question but needs an untested lifetime claim to do it has not won cleanly. The size of that dependency is stated for both products below.

Cotton rounds: cheaper per use than every disposable we priced

The reusable side of this comparison is a one-time price. LastRound is $16 for seven washable rounds with a travel case. A LastRound Refill of seven is $9. Both prices are from lastobject.com on 31 August 2026. LastObject's own pages state 250 washes per round. Seven rounds × 250 washes = 1,750 uses, the same 1,750 single-use pads the page says one set replaces. That figure is ours, and untested by us.

Prices read 31 Aug 2026. The two reusable rows depend on a manufacturer lifetime claim; the disposable rows do not.

The median disposable round is $0.0239. The cheapest thing on the shelf is $0.0200 — a 300-count private-label three-pack. At the claimed lifetime, the refill undercuts even that cheapest row by roughly a factor of four. The full set with case undercuts it by rather more than two.

Here is the same comparison in dollars per year, at one round a day, 365 a year. Single-use rounds run:

• $7.30 a year for the cheapest three-pack
• $7.81 for Equate
• $7.99 for up&up basic
• $8.47 for Swisspers
• $11.72 for Amazon Essentials
• $20.48 for Walgreens Premium
• $22.78 for Walgreens Organic

Against that span, $16 spent once breaks even in $16 ÷ $7.30 ≈ 2.2 years at the cheap end. At the expensive end it breaks even in $16 ÷ $22.78 ≈ 0.7 years, or about eight and a half months. Two rounds a day halves both figures. All of that assumes the pads survive the washing.

Facial tissues: the same result, on a narrower margin

LastTissue is $24 at lastobject.com. The set holds six organic cotton tissues in a two-compartment case, with a claimed life of 3,100 tissues. That is $0.0077 a tissue if the claim holds.

Prices read 31 Aug 2026, Target.com only for this category — see below.

The margin here is thinner than for rounds. Against a bulk four-pack at $0.0103 the reusable is cheaper by about a quarter. Against a pocket pack at $0.0497 it is cheaper by roughly six times. It leads the table on every row. But it leads the cheapest row by a margin small enough that a meaningful shortfall against the claimed lifetime would erase it.

And the price table hides the thing that actually decides this purchase: the set holds six tissues at a time. A box holds 120. Six tissues is a few hours of an ordinary cold, and refilling means running a wash, not opening a cupboard. The format the reusable really competes with is the pocket pack in a coat. Same size, same portability — and by some distance the most expensive tissue per unit in the survey.

The waste axis

Counted in units rather than dollars, neither comparison is close. Over the claimed lifetimes, one LastRound set stands in for 1,750 disposable pads and one LastTissue set for 3,100 tissues. Those are objects never bought and never binned. At one round a day, the disposable side of that is 365 pads a year plus three or four empty bags. The reusable side is one object kept, washed and eventually replaced.

We cannot put a mass on either side. No product page we opened publishes a per-unit weight. Ours does not either. So this axis is a count and nothing more. Washing has a footprint of its own, in water, detergent and machine wear. We have not priced it.

What the results depend on

Both reusable rows rest on a claim we make ourselves and have not measured.

The rounds. 250 washes per round is LastObject's figure. Break-even against a disposable does not need it. That comparison is arithmetic on two prices: $16 against $7.30 a year. It stands whatever the pads do in the wash. But the $0.0051 and $0.0091 per-use figures need the claim in full. At half the claimed life, per-use cost doubles. The refill would still sit under the cheapest disposable, and the set with case would land among the disposables rather than below them.

The tissues. 3,100 tissues is the same kind of claim. The dependency is stronger here, because the cheapest disposable is only about a quarter dearer. A serious shortfall against 3,100 turns a win into a loss on that bulk row. A wash test would settle both cases. Until it is run, these two rows are claims with arithmetic attached, not measurements.

A reusable has to be washed. That is not a footnote to the price; it is the mechanism the whole comparison runs on. A reusable left unwashed is not a cheaper product, it is an unused one.

What we could not price

• CVS.com: geo-blocked outside the US (HTTP 403 and an explicit block page) — no rows from a major pharmacy chain.
• Competing reusable rounds, priced but not rankable. Target sold its own up&up 16-pack with wash bag at $12.99. Target also sold a Glamlily set at $16.99. On that page the title says 18 pack and the specifications say 16 pads. Target also sold Tweezerman's six-pad set at $14.99, and Ulta.com listed that set at $16.50 the same day. All four prices were confirmed on the page. None of those pages states a wash count. So no cost per use can be computed for them, and none appears in the table above. That is an absence of data on our side, not a verdict on theirs.
• Amazon prices for the reusable products: Amazon renders the price via JavaScript after page load. Our own Amazon listings could not be confirmed verbatim, so they are not cited.
• Walmart.com and Walgreens.com blocked automated reads on the reusable categories (bot wall / HTTP 403), so those two retailers appear only in the disposable rows.
• LastRound Complete Set: $37 on 31 August, shown as a sale price against a $42 regular price. It was re-read at $40.00 on 2 September 2026. The pad count is not stated on the page either way. Its per-pad price cannot be derived, so it is excluded from every table here.
• The tissue category is Target-only. Walmart, Amazon, CVS and Walgreens all blocked automated reads on it. Seven rows from one retailer is the whole basis of that comparison.
• Washing costs cover water, detergent and machine wear. They are real and unpriced. They would soften both results by an amount we cannot state.
• Across the full 79-row survey, six rows failed verbatim price confirmation and are excluded from every article, including this one.
• Cotton swabs are not in this article. They were collected in the same survey and are priced separately. The answer there depends entirely on which disposable you hold the reusable against. Bulk value packs and precision swabs give opposite results, and that deserves its own arithmetic.

What would change this comparison

A per-unit gram weight from any manufacturer would let the waste axis be counted in mass instead of units. A confirmed CVS read would add a fourth pharmacy price point. A non-Target tissue row would stop that category resting on a single retailer. Most of all, a wash test on our own products would replace two manufacturer claims with two measurements. We would publish that result either way. The survey is re-run quarterly and date-stamped every time.

Disclosure: this article is published by LastObject, which sells the reusable rounds and the reusable tissue set named above. The lifetime figures those two rows depend on are our own claims. They are untested by us. They are labelled as claims in every table they appear in.
