Full Wireless Earphones COTSUBU STONE I have another pair of the same type of earphones, which I kept as a backup in case I lost the first ones. They are new and have been stored, so I haven't checked if they work. Please refrain from purchasing if you are concerned, as they have been stored at home. No claims and no returns are accepted. *I am currently selling these items to declutter my home. I will ship them as soon as possible via anonymous shipping, either Yu-Yu Mercari Bin or Kurakara Mercari Bin.
