Thank you for looking. *Opened, but unused.* ASICS Japan Volleyball Association Certified Model Knee Support XWP261 Set of 2 bags (1 piece per bag) Size: M Knee circumference: Approx. 32-38 cm UNISEX Suitable for beginners to advanced players Color: Black Materials: Main body: Rayon, Polyester, Cotton, Synthetic Rubber Pad: EVA I purchased these with the intention of playing vinyl volleyball with other elementary school parents, but we ended up not doing it, so they have not been used. I would be happy if someone could use them. I think they would also be suitable for junior high and high school students. Thank you for your consideration. Immediate purchase is OK.
