【Shureido】 Karate Uniform for Kata NW-3 (Extra Thick) New Wave 3 Top and Bottom, Size 0 Kata-specific uniform, Shureido New Wave 3. NW-3, top and bottom. Size: 0. Uses the new New Wave material (extra thick). The sound when performing kata and the silhouette are cool. Used in tournaments up to the 2nd grade of elementary school. It wasn't worn for practice, so it hasn't been used that much. There is some dirt on the collar, but there are no frays or tears. How about it for a child who loves kata!
