I purchased wireless earphones for the first time and used them once, but they didn't fit, so I'm selling them. The size S ear tips have been used, so I will discard them for hygiene reasons. Of the accessories, I will only include the M and L size ear tips. The main unit will be wiped with alcohol before shipping. Part of the box is torn due to poor opening. * Will be shipped via Yu-Yu Mercari Bin or Raku-Raku Mercari Bin. #GREEN HOUSE #Wireless Earphones
