This is a TS1 model driver with a 10.5-degree loft. - Model: TS1 - Loft: 10.5 degrees - Type: Driver - Head only - Weight: 118 grams (lightweight head) Thank you for viewing. The TS1 was developed as a small, lightweight head, released after the TS2 and TS3 models. It was not yet released in Japan at the time, so I went to Ala Moana, Hawaii, in the US to buy it as a trip. I think it suits Japanese people the best. It's a head that produced good data, with good initial ball speed and height. Why not give it a try? Highly recommended. There are small scratches and scuffs, so please check the images carefully before purchasing. We ship the next day after purchase. Thank you for your understanding. Shipping is free, so please refrain from price negotiations.
