We are selling a set of three different three-dimensional vaulting box puzzles. Previously, we sold the 10-tier, 11-piece, 21-piece, and 31-piece puzzles separately, but now we're offering them as a bundle. This is a much better deal than buying them individually. To assemble, you start with the disassembled pieces and stack them in order from largest to smallest. Because you have to consider the size of the parts as you stack them, people of all ages, from children to seniors, can enjoy it like a game. When storing the puzzle, you insert each level onto a skewer on the base, which should make putting it away fun. We were able to obtain hinoki wood at a reasonable price, so we were able to produce these puzzles. The pleasant scent of hinoki wood provides a sense of relaxation. This is an original design, so you can't buy it anywhere else. We are unsure if we will be able to obtain the materials to produce these again in the future, so please consider getting one now. Thank you. Feel free to ask any questions about the product, or for price negotiations. 【Materials】 Main body, base: Hinoki wood Top level: Hinoki wood, styrofoam, fabric, faux leather, brass nails 【Individual Dimensions】 〈When stored on the base〉 Width: 10cm, Depth: 8.5cm, Height: 12cm 〈Main body only〉 Width: 8.5cm, Depth: 5.8cm, Height: 11cm (Top level: Width 8.5cm, Depth: 4cm) #BuildingBlocks #Handmade #3DPuzzle #EducationalToy #Healing #Elderly #VaultingBox #Interior #Wooden #Goods #ToyObject Type...Building Blocks Type...Puzzle
