With TOY2, you can combine DUPLO® bricks with BRIO® wooden tracks, resulting in many more building and play possibilities than what the two major brands offer individually. This set includes 29 track connectors: 20 base connectors, 4 female switch connectors, 2 male switch connectors, 1 crossing, and 2 bending/anchoring connectors. TOY2 encourages children to rediscover perhaps already boring DUPLO®, HUBELINO®, BiOBUDDI®, Unico, and other compatible bricks with the almost forgotten BRIO®, IKEA®, Lillabo, Melissa, Hape, and similar wooden tracks. Foster children's creativity and let their imagination build entirely new constructions. The possibilities are very diverse and allow for stable building over two or even multiple levels. You can overcome thresholds or other obstacles, build bridges, and construct much more. The various parts are produced and packaged from recyclable plastic in Europe. The cardboard packaging is FSC certified, and the product is also CE certified. TOY2 is a fantastic toy for children and adults, providing fun whether playing alone, with friends, or with the whole family. Note: The TOY2 sets contain only connectors and no bricks or wooden train tracks. The colors of the TOY2 connectors may differ from the packaging images. Cleaning TOY2 track connectors: All TOY2 parts can be washed at 60 degrees, for example, in the dishwasher. There is a slight risk that parts may become slightly smaller or larger. However, this does not affect the anchoring of the tracks to the bricks. We recommend cleaning at less than 60 degrees or with disinfectants like alcohol or similar.
