【Set Contents】 This is a 5-piece set including Dr x 1, Fw x 2, and UT x 2. One of the UTs is brand new and unused. 【Material】 I believe the surface material is nylon fabric. Also, the lining is made of a soft material to prevent scratches on the club heads. With genuine products, which often use UP material, you may see deterioration such as cracking or peeling after 2-3 years. However, this product is made with durable materials and is less likely to deteriorate, so I believe it will last a long time and remain in good condition.
