Tangram wooden puzzle brain teaser mind game for kids and adults in cotton poach. Carefully pull out blocks, place them on top and hope you aren't the one who send the tower tumbling down! As more blocks are removed and the tower gets higher, it will become more shaky. Brand new, wrapped in cellophane, not touched. Tower size is 5x5x17.5 cm, 54 pieces, natural wood. Great present.
