I know these may seem like a novelty to some but I am really proud of how these Entropia sets have turned out -- they are a fun but *very functional* tool for securely creating private keys. And to boot they look kind of cool when you're not using them. $80 in bitcoin for a p2p purchase, shipping within the US is included, and purchases help fund my work on SeedSigner & other cold storage tools; DM if interested. Thank you RA for sharing this!
