Every company I've worked with with business in China or Russia does this. Same rule was implemented last year when there was a ban on laptops on flights to/from Iran and the other Muslim majority countries the US put travel restrictions on, despite being UK based.
The devices aren't given away however, they're just wiped and reused as burners. Not 100% secure as a nation state would have access to BIOS rootkits but it's better than nothing.
care to go into more detail about the glitter/nail polish? I've heard of the "straw" technique[1], flour/baby powder by the door, but never this stuff.
(chucking a random assortment of straws on top of your laptop then taking a photo, with the idea that it will be more difficult/time consuming/impossible to recreate exactly like in the photo).
