Power on and operation confirmed. This is a genuine product with a serial number. I purchased it 7 years ago, but I mainly went to a cosmetic dermatology clinic, so I didn't use it very often and stored it carefully. I handled it with care, so the main unit is in good condition, but the dedicated case has some peeling due to natural deterioration over time. *Returns and claims are not accepted, so please purchase if you understand this. Please refrain from purchasing if you are nervous.
