Due to this Puzzle being crafted as a limited edition or run, it is no longer available for sale. Regrettably we do not think it will be back in stock. Please view our other hard to find puzzles on our Karakuri Trick Box Page. A small number of Mame 18 Step Puzzle Boxes are available from a private collection. Each is STAMPED by Okiyama-san! Very rare and hard to find, each puzzle will arrive in it's original Izumiya box and instructions! Each box measures 1.75 x 1.25 x 1.25 inches. Mame boxes do have a minimal amount of imperfection in the yosegi. Most older mame boxes that I have seen have but these boxes operate perfectly and again are very RARE!
