Built-in speed glue effect, with the same speed and even more control. Desto F3 is somewhat faster than a traditional spin elastic rubber. Soft and dynamic, excellent control, and great sound of speed glue. Speed glue must not be used as damage could be done to the delicate sponge when removing the rubber.
