This is the 63mm version of the original Juggle Dream Bouncer! Designed and made by us, this is the ultimate bounce juggling ball with almost 100% rebound on a suitable surface. They come in a variety of swirly colours including white with green, red, blue and orange. The balls have a very subtle line around the center, but certainly not enough to affect performance. They may have slightly yellowish tints to balls, these are part of the manfautring process and have no effect on the performance of the balls. These balls are made from rubber so the temperature you practice or perform in may influence the bounce ration. There may be some very slight difference in bounce from ball to ball, but in our opinion, they still out perform a lot of expensive bounce balls and are great for the price. Price is for one ball. Weight=140g Width=63mm
