Thank you for viewing! ^_^ Shop Japan Rakuchin Hearing Rechargeable Ear-Hook Hearing Aid Hearing Aid, with Instruction Manual *One side only Retail Price: ¥23,000 It was a set for both ears, but I only used one side, so the main unit for the other side is not included. The remaining one side and all the parts are unused. *Please refer to the images. It seems that single-ear case sets are also sold, so I think it would be a good deal as it includes many replacement parts☆ Since I no longer need it, I am selling one unused main unit and two of each of the included parts ^_^ If you need it, please feel free to use it m(__)m *Please understand that this is a product stored at a private residence by an amateur and has been owned by someone once, so please purchase only if you understand this. Please refrain from purchasing if you are looking for a perfect product or are overly concerned about details m(__)m #HearingAid #HearingAmplifier
