The sustainable balls made of bioplastic are perfect for use in the TRIGEMA ball pool and are made of 100% bioplastic, which is obtained from corn starch and sugar cane. With these balls, you don't have to choose between antibacterial and environmentally friendly. This is because the food-safe materials, which are free from harmful chemicals such as BPA and PVC, leave a small carbon footprint and are 100% recyclable. Nothing stands in the way of carefree fun - especially as this is guaranteed in the long term thanks to the child-safe and hypoallergenic balls, which are more durable than conventional plastic balls! The ball set contains 200 balls.
