Black supporter with adjustable straps, - Brand: xenax - Type: Supporter - Color: Black - Straps: Adjustable Usable for junior high school students Thank you for viewing. I am selling it because I no longer use it. I used it about 2 or 3 times for sliding practice. I practiced on grass and a ground, so there is some grass and sand attached. For children debuting in junior high school For children who are not good at sliding I think they will improve.
