We carry Goshman Sponge Balls in the popular 2 inch size. This size works well for both stage and close up work. Sponge balls come as a set of 4 balls. We have regular and super soft available. They are red in color. The super soft are more compressible, and don’t spring out of the hand as quickly. I prefer super soft when working with children, as the balls aren’t as likely to spring out of the little hands, and go on the floor. Regular sponge balls are my preference when working for adults. The effect is that you hold a ball, and the spectator holds one. Yours vanishes, and the spectator finds it in his hand! Many more effects are possible. Comes complete with routine. 
Super Soft Sponge Balls set of 4 only $5.
