Bluetooth Earphones Heshikiri Hasebe Special "Touken Ranbu - Hanamaru -" ~ Setsugetsuka ~ ONKYO Onkyo OtoAni Used a few times, and they function without any problems. There is some paint chipping on the case. I have wiped them with alcohol, but please refrain from purchasing if you are concerned about use, dirt, or if you are a nervous buyer.
