This is a guitar strap from LIVE LINE's Tatami Edge series. The pattern is Kabi Yoshino/Black. I purchased it new on Amazon and used it for about two months, but I only used it for indoor practice, so I don't think there are any stains like sweat marks. I've attached round, brown felt stickers to the exposed metal fasteners on the strap ends to prevent scratches on the guitar (see photo 3). They can be easily removed if you don't need them, and I will send it as is. #LiveLine #JapanesePattern #Tatami
