Tenyo The most difficult plastic puzzle Diameter 11.5cm 24 pieces The easiest plastic puzzle 7 x 10.5cm 10 pieces Both are old items and have been stored for a long time. The cases have scratches and stains. The back of the difficult one has numbers written in pencil. Please understand. One piece of the easiest one has a slightly different color. Probably from the beginning. How about it for brain training, finger exercises, killing time, etc.? I hope you will make good use of them. Thank you.
