KAWAGUCHI Jersey Repair Fabric Navy: 2 packs Black: 1 pack This repair fabric is perfect for jerseys and stretch materials, and can be easily attached with an iron. Recommended for repairing tears and abrasions on sportswear and pants. I pre-applied it to my son's jersey when it was new. I felt like it prevented holes from forming, rather than applying it after a hole appeared. I used it when I bought new jerseys for him, up until around the time he was in the middle grades of elementary school, when he enjoyed sliding. 【Product Features】 ・Craft supplies made by KAWAGUCHI ・Compatible with stretch materials such as jerseys ・Cut freely ・Easy repair with iron-on application Unused, but stored at home. Immediate purchase is welcome.
