3x3x7 Cuboid from C4U
— the most difficult puzzle in the line of cuboids from the legendary Chinese cube manufacturer. This is the third in a row after 3x3x4
The quality of the puzzle do not raise any complaints: all the elements are casted good, the structure has a smooth rotation. Both large and small layers turn perfectly.
Stickers are bright, but for long term use, most likely, will be lifted up. Therefore, we strongly recommend you to buy an additional sticker set of our own production. On one of the central elements you can find a logo of a dinosaur of puzzle building — Cube For You company.
Despite the fact that the even cuboids are considered more difficult, the "reduction" step of 3x3x7 Cuboid will take you a decent amount of time.
