This is a set of 3 chin protectors for kendo, to be worn inside the men (face guard). They absorb sweat and prevent soiling. They are reversible, so you can use either side. The reverse side uses unused men towels (tenugui), so they should be absorbent. These are likely sized for upper elementary to junior high school students, but please use the dimensions in photo 3 as a guide. These are handmade and unused. Please wash them once you receive them. Please understand the above before purchasing. #ChinGuard #ChinSweatAbsorber #ChinProtector #Kendo #JuniorHighSchoolStudent #HighSchoolStudent #UniversityStudent
