Just because you are on the go doesn’t mean the puzzling has to stop! You can clip this mini 2×2 to your bag or even put it in your pocket. At roughly 3.5cm, it’s one of the smallest 2x2s you can get. It performs quite well for how small it is. Like most puzzles, it could benefit from some tensioning of the screws and a bit of lubricant. The keychain is also removable to make it easier to turn. You likely won’t break any records with it, but it is very playable and fun to show off to others.
