Yby is the first magnetic construction and balance toy made out of mycelium and bamboo, and is completely plastic free. It challenges the conventional design of wooden toys by using a system of arches and linear pieces that operates both in compression and in tension. This allows Yby to form organic shapes spanning in all directions. It is open-ended with a customised locking system to provide endless opportunities for play. Yby was developed in the belief that imagination is an essential part of childhood and that caring for the environment is the platform for their future. Yby is 100 percent plastic free and is manufactured using bio-based materials. Yby means ‘Earth’ in Tupi, an archaic language spoken by the indigenous peoples from Brazil.
