Absolute most beginner friendly way to generate your own entropy for beginners. Absolutely awesome to see. Although if I remember correctly they only post the 3d printer files. They don't actually sell these do they?
I want the average new bitcoiner to be able to buy these since most people don't have a 3d printer. I haven't looked into it though. Perhaps other companies sell these. I guess the issue with that is that what if it didn't have all 2048 words or had duplicates. People aren't going to verify the 2048 words one by one first.
