Butterfly Tenergy 05 has a unique feeling using a combination of Spring Sponge technology, High Tension rubber, and a tacky surface. It is excellent for imparting a great deal of spin on the ball. The designation of 05 in the name was adopted from Pimples Code No. 5. Tenergy 05 enables a full range of topspin play at or away from the table. It keeps its explosive power throughout the life of the rubber without the use of speed glue or boosting. Tenergy 05 is very popular among world-class table tennis players, including US Men's #1 Kanak Jha. Surface: Inverted Speed: 13.0 Spin: 11.5 Density: 36 To get the most out of your rubber, it is recommended that you clean it after each use and store it properly. Using our Racket Care Kit, use one pump of the Spin Refresh on each side of inverted rubber, then use the Rubber Care Sponge to thoroughly clean it. Once it is dry, apply your protective sheets and then place it in your case. Ideally, store your paddle in a climate-controlled space and avoid extreme temperatures for extended periods of time.
