New Technology QIJI Table Tennis Rubber.
Thickness: 2.1mm
OSMOSE INVERSE--Rubber Black Technology.
Because of sunlight, air, moisture and other oxidation factors, traditional rubber is easy to loss its stickiness. Under the "Osmose Inverse" technique, new type of molecular viscosity is very stable. Same time, new technique makes it possible for molecule to be stored in rubber inside the surface, new stickiness molecule will release and supply by itself, and ensure persistent sticky of rubber surface.
