Great products you are selling.
Its a nice branch of the cryptosteel concept.
This is one level more permanent because they letters are actually stamped into the plate.
I already have a cryptosteel, but I will consider ordering this one as well, not for collection, but for use.
About price... if you are storing thousands of dollars worth of BTC (which potentially could be worth millions one day) on a hardware wallet, there is really not any good argument not to pay those 100 USD more and have an extra level of protection (imo).
Question:
The dies you are selling, are they fair or just a toy?
