● BG66 ULTIMAX Single String 18-Piece Set ● You can string approximately 17 to 19 rackets with a standard 200m roll. Unlike a roll, there's no need to measure and cut each string individually, making it convenient. We sell the 18-piece set because it's the limit for packaging size and the number of rackets you can string is the same as with a 200m roll. Cannot be combined with different colors. ● Genuine Product for Domestic Sale ● Manufactured at the YONEX Tokyo factory. Stored in a cool, dark room with the utmost attention to quality. ★ Product Description ★ Product Name: BG66 Ultimax 10m x 18-Piece Set Color: White (430) Size: 10m per string Construction: Multifilament Material: Core: High-strength nylon Side: High Polymer Nylon (Braiding Processing) Country of Manufacture: Made in Japan Selling Price: ¥31,406 (including consumption tax, shipping, and sales commission) Product Features: Genuine YONEX JAPAN product.
