Ilius B is the first long pimpled rubber with “Absorber Sponge Drop” technology developed by Butterfly. The top sheet is rather hard with pimples whose aspect ratio is at the highest limit permitted. The combination of the top sheet and “Absorber Sponge Drop” provides high performance when playing short over the table, such as chop block. In addition, innovative attacking and defensive play are both possible, making best use of the characteristics of the long pimples, such as a low backhand shots with minimal spin.
