Mainstays (String Savers)
Prolong string life ... Enhance your sweet spot!
String Savers are the ideal accessory for players who hit with a very high degree of topspin.
They reduce mainstring movement so that friction burn is virually eliminated.
They are designed to be highly effective with the least amount of tension gain of similar type products.
The high grade nylon composition is synergistic with the string bed.
The circular configuration of the attachment device promotes efficient installation.
The pack comes with 160 pieces in the applicator which is enough to cover up to five restrings.
