Solid! Such fantastic balls that are solid on every hit and bounce. They don't crack under pressure and have a nice feel.
Very nice quality
Super happy with the product.
I bought them for a gift for my girlfriends dad and me and him play ping pong every time we go over there and I got the 4 star ping pong balls and he loves them and so do I, it was a great gift and I will buy more in the future. Keep up the good work 5/5!!!
4 star balls
