Water-based glue specifically suitable for smooth rubbers; You should apply a couple of layers on the rubber and 1 to 2 layers on the blade. The glue increases the slingshot effect of the rubber. When you have to detach the rubbers, it has the exceptional ability to create a film on the rubber or on the blade that’s very easy to remove, leaving them completely clean. The glue complies to the International Federation ITTF and FITET guidelines. It comes in a 100 ml package with a tweezer and comfortable sponges to apply the glue.
