I am a starting magician (I started September 2017) and I want to get myself a set of sponge balls. I found these sponge balls on E-Bay: https://www.ebay.com/itm/4-Red-Magi...oQAAOSw0AxZlMQY:sc:USPSFirstClass!07666!US!-1. I am aware that Goshman Sponges are the standard, but I wanted to know how well these are. There also is a 2-inch variation from the same company on E-Bay. Thanks for any help!
