RED…Worn only for two days during practice games due to color designation. It's in very good condition. Blue…Used once a week for practice for a year. There is some pilling due to wear. Regarding the size… My son is currently wearing 17-18cm, so I think it's smaller, KL: equivalent to 15-16cm. (He wore them when he was in his final year of kindergarten) These are used items. Please purchase only if you understand this. ஐ
