Used a few times a year, with some minor scratches. The Velcro's adhesive strength and the belt function without issue, and I believe it can be used without any problems. Adults have worn it, but I think it's originally for juniors. There is no size indication. This is a used item with a sense of wear, so please refrain from purchasing if you are sensitive to such things. I am listing the same product, so I have put a tape with "2" on it to avoid confusion. I will remove it when shipping. 【Product Description】 A body protector that covers not only the chest and torso but also the collarbone area. The impact-absorbing material is EVA rubber sandwiched between urethane foam. The back is also Velcro, allowing for quick fastening. It's a reversible design, convenient for matches. When used with low-rebound boxing gloves and a PC safety head guard, it allows for hard training assuming face-contact rules. ■Size: Jr Size ■Thickness: 2.5cm ■Weight: 650-680g ■Color: Red x White *Reversible type ■Material: Synthetic leather
