QiYi 3-Layer Cylinder

QiYi 3-Layer Cylinder

A 3×3 mechanism inside a cylinder instead of a cube. The three round slices turn against each other and the vertical cuts split them into segments, so it solves like a 3×3 with two of its faces missing — easier than it looks, and unlike anything else on a shelf.

Stickerless, smooth, and cheap enough to be a gift rather than a purchase. A good display piece: people pick it up because they cannot tell what it is.

Stickerless · non-magnetic · 3×3 shape mod.
