Bouncy ball that fits in your hand and is made of natural rubber. Great for kids, party bags, dogs, and handball! Diameter of each ball: 5.7cm PVC-free and carries the CE mark (European safety standard). Recommended for age 3 years plus. Made in Taiwan because no-one makes this kind of thing in Europe at the moment. Rubber trees don't even grow here! So these are as eco as we can find when it comes to rubber balls :-)
