The ZinkoTek System combines creativity and construction to create imaginative play structures. The basic parts of the building system are made from 100% recyclable EVA, soft, yet sturdy, foam. The set is designed so that a 3 year old can sort, connect and stack in a variety of ways, while an older child can build larger scale structures such as a play house, jet plane, robot, or smaller tabletop objects — ALL WITH THE SAME SET! With 276 pieces, ZinkoTek offers endless possibilities that will captivate boys and girls of all ages. Completely weather-proof, the ZinkoTek System is equally fun indoors and out. Your child's buildings will change with their environment. ZinkoTek is truly a system that grows with your child.
