This is a set of two 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 a new men towel (tenugui), so it should be absorbent. This size is estimated for upper elementary to junior high school students, but please refer to the dimensions in photo 3. These are handmade, unused items. Please wash them once you receive them. Please understand the above before purchasing. #ChinGuard #ChinSweatAbsorber #ChinProtector #Kendo #JuniorHighSchoolStudent #HighSchoolStudent #UniversityStudent
