YJ Floppy Ghost Cube

Definitely a challenge but overall fun.

The world's hardest floppy cube.

Would you believe that this thing took me a full half hour to solve? It's deceptively difficult, as the 5 axes result in situations that you wouldn't encounter on a standard 1x3x3 four sided puzzle. If that wasn't bad enough, the "ghost" nature of it constantly makes you end up placing pieces where they don't actually belong, and being all one single color means that you can't tell when looking at a piece which of the 10 combinations of position/orientation it should go in for a corner piece, or which of the two orientations it should go in for an edge piece (ok, that's a slight lie because the "brushed metal" design of the stickers make the edge orientations obvious, though one edge _almost_ looks correct when it's oriented wrong). By my math, this puzzle has over 60,000 possible piece arrangements (and given the odd number of sides, I don't think there is much in the way of parity to make the number of possible scrambles that much lower). So in the end you have a little puzzle that is great to fidget with, takes actual effort to solve, and slips effortlessly into a pocket. Ok, enough about the difficulty. What about the puzzle quality? Well, the pieces rattle a little, but still feel solid enough when you turn them. It can corner cut ever so slightly, but not enough that you won't run into lockups from time to time. Due to the trapezoidal shape of the edge pieces, you can't make any quarter turns of two sides and then turn the edge in between them much like you can on a normal floppy cube (technically you could force this move, but it's clear the puzzle isn't meant to move in this way, and I believe if you did this you'd make the puzzle "unsolvable" without repeating the action). The only downside is that it's stickered, and as such it's going to have a limited lifespan if you keep it in your bag or pocket (though in theory you could remove all the stickers and it'd be just as solvable, and in fact even a little harder due to the lack of clues as to edge orientation).
