Shin-Kyokushinkai uniform top and bottom set. The tag came off in the wash, but I think it's size 1. I wore it from 1st grade to 3rd grade of elementary school. It was used for training, so there is a feeling of use. There is no name written on it, but there is a mark where a sticker that was ironed on was peeled off on the lower left of the back of the uniform (Image 7). If you understand, thank you.
