Mizuno Karate Fist Supporters. SS size These can be used in official matches. How about these for those who have just started learning, or those who are participating in kumite for the first time? In our family, we were able to use them until the 6th grade (although we only used them during tournaments, so the number of times used was less than 10). As mentioned above, since they were only used during matches, there is little wear and tear, but there is some slight fuzzing on the rubber part where you insert your fingers. It's not even visible in the photos, but if you are concerned, please refrain from purchasing. There are no problems such as the rubber of the fist supporters stretching out. The name on the size tag will be blacked out, and the item will be disinfected before shipping. Please understand that these are used items, and we appreciate your purchase. I think they are relatively in good condition, but if you are strict about the term "good condition," please refrain from purchasing. Please note that we cannot lower the price for a while due to shipping costs.
