@threed @nitrokey The glitter is suspended in the liquid. A picture is taken once it hardens. That pattern that the glitter forms once it hardens is random and very hard to recreate. You can't get the bottoms screws off without chipping or removing the glitter thereby ensuring that the case can't be opened without visible evidence.

We do this too for our Purism laptops and have for a while now.
