Convolution Ball Extra (Wenge)
by Stewart Cofin & Pelikan
We used 2 kinds of hard wood: Wenge and Maple.
Diameter of the ball is 90 mm.
Puzzle is made of 7 different checkerboard pattern styled parts. Be careful, this puzzle includes rotation and it has only one method of composition. We really recommend this puzzle, it is top product of our company. In the stand which is part of this product is placed the logo of our company.
