These are high quality Goshman sponge balls. Unlike the Super Soft ones, these are a bit harder to compress but I actually prefer that. When the spectators hold them, they know that they are a bit firm giving the illusion that it would be difficult to conceal three in my hand. Of course I don't mention any of that to them though or it would be obvious. Also, I actually enjoy using the firmer balls anyways. It all depends on what you like. Try some of these out and you'll like them.
