About this Product
This is a Skewb with two-fold stretched "face square" (aka Offset Skewb) and with four additional dino-cuts. Like a Master Skewb, it has 3x3x3x3 cuts system, but each one cutting layer of a pair is moved so it cuts vertices, thus reducing the number of elements and making the puzzle much easier to solve. On each face one can see a Cyrillic letter Ф (or Greek Phi) which is read as F, that's why I named it F-Skewb.
Puzzle edge size: 57mm. Additional parts required: 4x M3x6 DIN 912 screws.
