Puzzle de poche Metal Fifteen

I've owned plastic versions before and this metal one feels way sturdier in your hands. The scramble combinations genuinely keep you busy, though my commute is now mostly me hunched over this thing.

The metal tiles slide with a satisfying click and the frame feels solid in my hand, way better than the flimsy plastic version I had as a kid. I've been scrambling and re-solving it on my desk all week and it still hasn't gotten old.

I'd never actually solved one of these before, and the metal tiles have a nice weight that makes sliding them weirdly satisfying. Got it for my desk at work and now I lose ten minutes every time I pick it up. Still haven't beaten it, but I'm not mad about it.
