This is the charging case for the EarFun Air Pro 3 tw500 in black. I have confirmed that it opens and closes, and that it powers on and charges. There are some scratches and scuffs from normal use, but it works without any problems. This is recommended for those looking for a fully functional item. It is recommended for those who don't mind a few scratches or scuffs. This is recommended for those who have the earphones but have lost or damaged the case. Please consider this with confidence! Also, since this is a used item, please refrain from returns or claims.
