GAN 328 Keychain 3×3 (28mm Mini)

The GAN 328 Keychain is a proper miniature 3×3 instead of a novelty. It turns, it corner cuts, and it solves with the same methods as a full-size cube, allowing for the fact that 28mm makes finger tricks a challenge.

The GAN 328 Keychain measures 28mm and uses tiles instead of stickers, which matters at this size because stickers on a cube this small lift almost immediately. It ships in a clear clamshell case, and the keychain attaches to the case.

That is the sensible part of the design. Clipping a keyring to a cube ruins the cube. Here the clasp locks the case shut and the cube stays inside, so it survives being carried on a bag.

It works as a stocking filler, a desk fidget, and the cheapest way to give somebody a cube that actually works.
