I am selling these items due to decluttering, which I purchased several units of four years ago. New electrode plates, electrode cords, and masks are included ( ¨̮⋆) Please prepare your own solutions for introduction, such as placenta and vitamin C derivatives. This is an iontophoresis device with three modes: 1500, 4500, and 15000 Hz! It is effective for soothing the skin, promoting turnover, etc. High frequencies can be used for the epidermis, and low frequencies can be used for the dermis. Please refer to the six photos for details. The following five items are included: Main unit, 8 cords, 16 electrode plates, 2 masks, and a copy of the instruction manual. Shipping will be via Yamato's anonymous delivery service. We plan to ship within 1-2 days. We will pack carefully to prevent damage. Qualified invoices can be issued. If you need one, please let us know before purchasing, and we will prepare the documents! We have confirmed the operation before listing. Each pattern, 3 output levels, and operation are normal. If the +- electrode plates remain in contact during use, the safety device will prevent the device from operating, so please insert only the necessary cords and electrode plates! The exterior has minor scratches, but there is no noticeable deterioration overall. The parts are also new, so the cords and masks are in very clean condition! We have taken many photos, so please check them! Are you interested if you understand that these are used items? Also, even if you are new to Mercari, please feel free to ask questions (ᴗᴗ ) We will respond carefully. Thank you! Biotron 7 BIONIC CELLCER
