Way too expensive, and the makers of the OpenDime sell what amounts to exactly the same thing (on the coinkite website, linked
here, you'll find it as the Opendime Capsule). And it's only USD $13.99. I have one of these and you can definitely fit a Nano S into it with room for padding, though the Nano X doesn't fit.
I like the idea of this kind of storage, which is why I bought one from coinkite--but as NeuroticFish has pointed out, you can find something similar that will do the job just fine for a lot cheaper than what OP is trying to sell them for.
Than you don't need any capsule, just buy waterproof plastic zip bag for 1$ and put your hardware wallet inside.
I guess if you were planning on burying this somewhere, the waterproof aluminum case would come in handy, unlike a Zip-Loc bag. I'm not sure how many people have buried anything related to crypto, but I'm sure there are at least a few out there for which a case like this would be useful.
