Important update

I'd only be interested if it actually works and could be used to sand tiny things.

There was a mini Miluakee tape measure keychain I got at a checkout for my wife. It's super helpful though, it was great for measuring furniture at stores. Goes out to 6 feet or something.

There are gacha capsule machines in Japan with miniature models of all sorts of branded goods, from obvious ones like cars and sneakers to hi-fi systems, musical instruments, network switches, power tools and more, all modelled and manufactured to a higher quality than the capsule-machine toys sold to kids in western countries. Some people do like spending a few hundred yen (i.e. a few dollars) to collect small models of things.

Labubus for dads.

If you put these in a machine with yellow, red, and blue versions of the tools it would make decent money. especially if red was the rarest color.

I want a working one that I can give to a Barbie or similar doll.
