Thank you for viewing. I am selling these because the size didn't fit. This is a set of 4. Z-DRAGON (Jichodo) arm covers, brand new and unused. I can also sell them individually. They have a cooling function, providing a cool feel when worn. They are UV cut, making them recommended for sports and outdoor work. 【Product Details】 ・Product Name: COOL ARM COVERS ・Size: M ・Color: Black ・Material: 90% polyester, 10% polyurethane ・Functions: Cooling function, UV cut ・Uses: Sports in general, outdoor work, etc. Although they are new and unused, please understand that they have been stored at home before purchasing.
