The original Oddball! 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, white with: purple, green, red, blue, yellow, orange, black and all white. The balls have a very subtle line around the centre and a slight 'The Oddball' embossing at one end, but certainly not enough to affect performance. These balls are made from rubber so the temperature can influence their performance. 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.
