Paperwallet Micro Wallet: where the maker’s figures and outside measurements agree

A wallet made of Tyvek, the synthetic paper used for express envelopes and building wrap — printed with artwork and folded down to roughly the footprint of a credit card. Eleven years and five funded Kickstarter campaigns sit behind it. An outside reviewer’s measurements match the maker’s published figures, and two independent reviewers, three years apart, report the same weakness.

Maker: Paperwallet, founded by Elad Burko. The Kickstarter creator profile gives Valley Stream, NY
Price: US$39.00 for a Micro Wallet in any of the current artist designs, on the maker’s own store. Older designs are discounted to US$25.00 and the Slim Wallet is US$29.00. Confirmed on 7 August 2026 and may change.

Eleven years of campaigns, and they are all still readable

Most of what we look at has one campaign behind it, and often a creator who has never run another. This is the opposite case.

Source: the creator page, read on 7 August 2026. The account was opened in July 2014 and last logged in on 3 July 2026.

Kickstarter has attached three of its own badges to this creator: Backer Favorite, Repeat Creator and Superbacker. The last of those is not about selling — it is awarded for backing other people’s projects, and this account has backed 84 of them. That is not proof the product is good. It does describe somebody who has been on the other side of the transaction eighty-four times.

The 2018 campaign in detail

An update posted in 2025 on a campaign that closed in 2018 is worth pausing on. Seven years after taking the money, the page was still being used to talk to backers. The page did not go dark, which is the usual pattern.

Two reviewers had it, and they agree

Kristyne Defever reviewed the Micro Wallet at Pack Hacker, updated 11 April 2023, with the wallet in hand and a documented usage timeline covering at least two weeks. The score was 7.2 out of 10. Bob Patterson reviewed the Slim Wallet at The Gadgeteer on 24 July 2020, after what he describes as a month of steady use.

Both disclose their position, which is rarer than it should be. Pack Hacker states at the top of the page that it earns affiliate commission on purchases through its links. The Gadgeteer states at the end that the sample was provided by Paperwallet. Neither hides it, and we would rather cite two reviewers who declared an interest than one who did not.

The measurements matched

The two dimensions the maker publishes are within a rounding step of what an outside reviewer reported, and the capacity claim is confirmed with the mechanism explained. Putting a maker’s figures and an outsider’s figures side by side and finding them in agreement is rare in this category. The reviewer also supplied the two numbers the maker leaves out.

And they found the same fault

Three years and two publications apart, both reviewers describe wear appearing quickly, and neither describes the wallet failing.

• Pack Hacker, after two weeks: the Tyvek is “definitely looking worn in”, with creased edges at the fold plus nicks and dents in the material.
• The Gadgeteer, after a month: the material will not rip or tear and sheds water, but the wallet is “getting a bit of a well worn look”.

The Gadgeteer adds a functional problem the maker’s page does not mention: cards can slide out of the open flap pockets. The reviewer found cards loose in his bag and recommends keeping important cards in the window slots only.

So the honest summary is: the material holds up structurally and looks scuffed within weeks. Whether that is a defect or the point of the thing depends on the buyer — a wallet printed with artwork and sold as pocketable art is not aiming at the same target as a leather billfold.

What the maker publishes

One detail is worth drawing out. The maker publishes a guide titled “How to Make Your Tyvek Wallet Last 5 Years”, and publishes no warranty at all. A five-year expectation is set on the blog; nothing on the product page commits to it. A returns policy exists in the footer. Those are different promises, and only one of them is enforceable.

Pros

• Eleven years and five funded campaigns behind the product
• The maker’s published dimensions and capacity match an outside reviewer’s report
• Two reviewers who had the product, at real publications, both disclosing their interest
• 8.5 g and 0.125 in thick, by outside measurement — genuinely small, not just marketed as small
• An RFID-blocking lining at US$39
• Thirty-one artist designs at one price, and the artists are credited

Cons

• Visible edge wear within two to four weeks, reported independently by two reviewers three years apart
• No warranty published, alongside a maker’s guide that talks about a five-year life
• Weight, thickness and country of manufacture are all absent from the product page
• Cards can slide out of the open flap pockets, per a reviewer of the sibling Slim Wallet
• No published test of the RFID-blocking claim
• US$39 for a wallet that will look used within a month is a taste question, not a value one

Where this leaves a buyer

Buy it if you want the artwork and the thinness, and you accept that it will look used within a month — two independent reviewers three years apart both report that. Do not buy it expecting leather-like longevity: no warranty is published, and the maker’s own guide talks about replacing it.

FAQ

Does it fall apart?
No published account we found describes one tearing or failing. Both reviewers describe the opposite: the material holds, and it scuffs. Expect creased edges and marks within a month.

How many cards does it hold?
Eight, two per slot across four slots, plus cash. The maker’s claim and the reviewer’s count agree.

Is it waterproof?
The maker says so, and one reviewer describes it shedding water. Neither is a submersion rating, and none is published.

Did the Kickstarter backers receive it?
Two of the five campaigns carry Kickstarter’s “Marked as fulfilled” label, which the creator sets. The 2018 campaign’s page was still being updated in 2025 and its 977 comments remain open to read.

Is US$39.00 the real price?
It is the price for the current designs on the maker’s store on 7 August 2026. Older designs were US$25.00 the same day. Check before you buy.
