This is a set of accessories for the Kichokichi HA5 portable hearing amplifier, excluding the main unit and batteries. (According to the manual, the neck strap was not originally included but was purchased separately, but I'm including it since it was stored together.) It runs on one commercially available AAA battery. [Items Included] Kichokichi HA5 Main Unit: 1 Single-ear Earphone: 1 Separate Neck Strap: 1 (Adjustable size) Warranty Card: 1 Instruction Manual: 1 Size Main Unit Folded: Approximately 3.5 x 9.5 cm Opened: Approximately 2 cm x 18 cm Single-ear Earphone: Approximately 114 cm [Condition Description] Operation confirmed. Lightly cleaned. Non-smoking environment, no pets. There is a small tear in the soft cover of the earphone (it shouldn't affect use). Also, there is some dirt on the back of the sticker that says 【Earphone Jack】 when opened, and there are small scratches and paint chips on the paint in some places when closed. (Please refer to photos 17-20.) The instruction manual has water damage and a hole, but there is no odor, and the hole's location and size do not interfere with reading the text. The main unit will be wrapped in cardboard and bubble wrap when opened, and the box will be folded for shipping. If you have any requests regarding shipping, please consult in the comments section. Please understand that this is a used item stored at home.
