This is a set of two tennis strings from the photo. I'm selling them because I changed strings and no longer use these. They have been used, so the amount is reduced. I don't know how many times they can be strung, so please judge from the photos. If you feel it's a good deal, please consider purchasing. The white marks on the case are from removing stickers, I apologize. Thank you for your consideration. 17-gauge polyester tennis string that combines power and spin. - Brand: SOLINCO - Model Name: HYPER-G - Gauge: 17 gauge / 1.20mm - Length: 656 feet / 200 meters - Material: Polyester - Characteristics: Power, Spin Thank you for viewing.
