Children will have fun building intricate three-dimensional structures by interlocking the 4 types of tubes (the STRAIGHT, the TURN, the T-SHAPE and the CROSS) in infinite combinations. They will create mazes of water pipelines, modular space stations, scaffoldings, buildings, animals, even blowguns... and anything else suggested by their fertile fantasy because TUBATION is a very adaptable construction system. TUBATION is suitable also for younger children because it doesn't include small parts and all pieces are pleasant to handle and totally unbreakable. TUBATION stimulates children's logic thinking and creativity while developing their manual skills. This product ships in approximately 1 days
