The main pieces are all present. Includes one booklet and the original box. The marbles may be from other sets, as we added some to play with. Current retail price: 25,300 yen The black rubber parts act like a trampoline, causing the marbles to bounce. The marbles jump over obstacles and gaps, adding a fun element to the game. The item is in relatively good condition, but please understand that it is a used item that has been played with by a child and stored at home. Please refrain from purchasing if you are looking for a new item. I have a cat, so cat hair may stick to the packaging. - Brand: cuboro - Product Name: cuboro jump - Material: Wood
