Wooden building blocks (x12)

The wooden blocks make stacking a bit tricky. Thanks to their special shape with 18 or 20 sides and different sized contact surfaces, the blocks can be combined on top of each other in either an upright or laid down position until the tower becomes so unstable that the structure collapses. Building requires skill and dexterity. Features - Dimensions: Largest block: 5x3.8x3.8 cm, smallest block: 3.8x2x2 cm - Material: Birch wood - 12 wooden stones (3 different sizes)
