This is a yellow tennis string known for its high spin performance and control. It has a long-selling history with a loyal following. This string is used by Yūki Matsuo, a famous pro with many subscribers on his YouTube tennis channel. It is 1.30mm gauge. It has been used 3 times, so if your racket size is 100 inches, you can string it 14 more times. The "14" written over the "17" in the photo is to remind me how many times it can be strung. The black marker above is where I wrote my name, which has been erased. Please understand this before purchasing. No returns or refunds. I will sell it for about half price. Thank you very much. - Brand: Babolat - Model Name: RPM Hurricane - Color: Yellow - Length: 14 stringings remaining (3 uses out of 17) - Gauge: 1.30mm Thank you for looking.
