This is a set of two half pants worn by Taiwanese Yonex players Wang Chi-Lin and Chou Tien-chen. The size is XL (equivalent to JP's O). Purchased in Taiwan. The white pair has been used about 10 times, and the blue pair about 5 times. They are thin and suitable for spring and summer. Tags are also included. While there are cheaper Asian-market products, Yonex Taiwan products are priced similarly to domestic products, costing around 7,000-8,000 yen at the time based on the exchange rate. Would anyone interested like to purchase them? Thank you.
