The new Optiborn puzzle was designed by french designer Stéphane Chomine.
We used Padouk and American Walnut.
It measures 44mm x 66mm x 44mm.
Puzzle is made of 4 parts placed in a cage. Difficulty 36(18.104.22.168)
An unusual elegant puzzle, very satisfactory when the last piece slides in.
Name of the puzzle is engraved on it so there won't be no commutation.
