Neat tamper-evidence packaging concept: a random pattern of beads that's modified when you open the package, along with a smartphone app to automatically verify the pattern is correct.
Reusable glitter basically: to fake a seal, you need to make the significant effort of positioning each bead in the right place. Possible. But very time consuming.
I'd buy one!
@pete good question. I don't really know, but I think their intention was to use it as a hardware wallet manufacturer to discourage interdiction. So off-the-shelf isn't required.
The food storage vacuum system sounds like a great idea. I know they had to experiment a bit to find these little black balls which moved very randomly inside of the bubble. Used some kind of industrial lubricant powder or something.
