Good point! I don't exclude to test more this capsule at some point, possibly with a Ledger inside, by throwing it into flames for a few seconds or even minutes to see what happens. I've also had doubts about the practicality of this product. However, when I came across the Cold Wallets Case (by Black Seed Ink), which has a fire resistance up to 600°C / 1112°F, it certainly adds a level of logic and looks badass.
