STIGA SYMMETRY. Symmetry is a NEW short pimple rubber. Made in Japan, it has been carefully developed and adapted for the ABS plastic 40+ ball. The elastic sponge and built-in speed glue effect gives this short pimpled out rubber high speed and excellent spin generating possibilities. Its new offensive pimple design creates topspin as well as effective blocks and is great for punchy counter attacking strokes close to the table.
