I apologize, as this item was stored at my parents' house and I don't have detailed information about it, but I believe it's a Descente supporter. The size suggests it might be a junior elbow pad... but I'm not certain. I've attached photos of the item with size information, so please take a look. Because of this, I've priced it affordably. I would be happy if someone who understands and can use this item would purchase it. #Descente #Junior #Supporter
