Seed Phrase Backup evaluated across whether someone neutral actually destroyed one, where the fire number comes from, what you can store and recover, and whether the real landed price is on the page.
Ranked here: seed phrase backups that you buy so your seed phrase can still be read and recovered after a fire. Not ranked here: products that do not store a seed phrase to be read and recovered after a fire.

Decision guide
What matters most before choosing in this category
Buy the tested one, not the rated one. This is a rare category where the marketing claim is physically testable, and an independent tester has been destroying these products for years — so a published temperature is worth far less than a grade from someone who put the thing in a furnace. The split is uncomfortable and consistent: the products that failed are the ones quoting a number, because that number is their alloy's melting point, which is a property of stainless steel rather than a result for the product. The two that publish no rating at all take straight A grades, and one of those is the cheapest thing here. After that, ask whether you could still read the phrase after the damage — surviving intact and staying legible are different tests — and only then compare price.
Has a neutral third party actually destroyed this product, and what grade did it get?
Is the quoted temperature a test result, or just the melting point of the metal?
If it survives a fire, can the phrase still be read out of it?

Two engraved stainless sheets, 12 words each, marked with an included automatic punch.
Two engraved stainless sheets, 12 words each, marked with an included automatic punch. Strongest on where the fire number comes from (10/10): BitBox's Steelwallet page publishes no fire temperature of its own. It quotes Jameson Lopp's independent stress test, "Using the center punch went smoothly and quickly. No data loss.", and links the review. Read by hand on 10 November 2026. Weakest on whether the real landed price is on the page (6/10): BitBox prints the price, €65.00, and the tax basis, 19% VAT, on its shop page. The shipping cost is calculated at checkout and is not on the page. The page said shipping was free in August and no longer says so. Published price: BitBox shop (https://shop.bitbox.swiss/en/products/steelwallet-13/), read 10 November 2026 by hand in a browser; the page answers plain clients with a Cloudflare challenge. "Steelwallet €65.00 including 19.00% VAT".
Best forWhere the fire number comes from — 10/10
Main tradeoffThe A grade is from May 2019 - seven years old - and Shift Crypto quotes that review on the product page as current evidence. Nobody neutral has destroyed a Steelwallet bought from shop.bitbox.swiss. Shipping is not on the page: BitBox's shipping policy, read by hand on 10 November 2026, says "The shipping price is calculated during checkout based on the weight of the product, destination country and selected shipping speed.", so the €65.00 is not the landed price.

Frequently asked
Questions people ask before choosing seed backup
Does a higher temperature rating mean a better backup?
No, and in this pool the correlation runs the other way. A stated rating is usually the melting point of the alloy — a property of stainless steel that any product made from it can claim — not a result of testing that product. One backup advertised a fireproof threshold of 1399 to 1455°C, which is very nearly the published melting range of grade 304 steel, and lost the seed roughly 300°C below it. Another prints the melting point and the fire rating as the same number, two paragraphs apart on the same page. Meanwhile the two most credible products in the pool publish no temperature at all. Treat the number as marketing and the independent grade as evidence.
Why weight independent testing so heavily?
Because it is the only claim in this category anyone can check, and because the failure mode is undetectable until it matters. You will not learn that your backup was inadequate until after a fire, by which point the phrase is gone. Jameson Lopp has published fire, crush and acid results across dozens of these devices, and one vendor in this pool links to those results directly from its own product page — which is a meaningful signal in itself, since the products with the most to hide point you at their own marketing instead.
Is surviving the fire the same as still being usable?
Not at all, and they are scored separately here for that reason. A plate can come out of a furnace structurally intact with the stamped letters deformed or the tiles fused, which is a device that survived and a backup that did not. The tester's own framing is useful: a capsule seizing shut is not a critical failure, because the phrase is still recoverable by someone willing to cut it open, whereas illegible characters are terminal. Ask what state the phrase is in afterwards, not whether the object still exists.
