Camouflage Mirror 4x4x4 Cube Black Body with Silver Label (4x4x5 core-cube, Lee Mod) This is a hand-made puzzle by Lee. The puzzle design is beautiful and has very nice stickers. The puzzle consists of a center-shifted 4x4x5 cube as the core part, and 3-D printing outer parts. This is different from the normal mirror 4x4x4 cube. The inter-mediate shapes will have 5 layers and also 6 layers. The shape shift is more interesting and complex. Much higher difficulty level and more fun. The turning is smooth. It is good for collection and also a challenge to solve.
