Racket covering black technology : “Osmose Inverse” technology.

Adhesive for the tradition racket covering is easy to be lossed because of the oxidation reaction between tradition adhesive molecule and sunshine, air, and water.

While the chemical state of the new adhesive molecule is very stable and not easy to be lossed.

Moreover, “Osmose Inverse” technology can make the new adhesive molecule store inside of the rubber not outside of the suface as traditional technology.

Under the premise of the loss of rubber surface, the ne adhesive molecule can release supplement by themselves, and make sure the rubber surface keep the durable adhesive.

With Double Fish new patent technology “Osmose Inverse”, QIJI rubber contains “new viscosity molecular”, which will maintain the stickiness of rubber surface.

Using hard and high-elastic sealed cell sponge, and after swelling of glue filling, this rubber provides player with power-up feeling, so it is especially for quick attack.
