This model offers both durability and all-around performance, making it a reliable string for club activities, practice, and matches. Purchased around 2021. It was purchased new from a sports shop and stored in a dark place. The outer packaging has some scratches and minor damage from storage, and a price sticker is attached, but the string itself is in new condition. M-TOUGH 70 features MIZUNO's unique "TOUGH RESIN" material, which is highly durable and resistant to abrasion and impact. The 0.70mm gauge is a well-balanced thickness, not too thin and not too thick, providing both a direct hitting feel and resistance to breakage.
