※ I am also selling this on other platforms, so please be sure to comment before purchasing. I purchased this in September 2019, but the usage frequency was low, so the main unit is also in excellent condition. The handpiece has also been completely replaced once. You can feel the effect with just one use! Three 3.0mm cartridges, partially used: (Remaining shots = 700 shots, 435 shots, 245 shots) These are included, so you can use it immediately. Operation has been confirmed. Accessories: Instruction manual, handpiece, two types of power cords, gel 【Product Specifications】 External dimensions (width x depth x height): 380 x 300 x 140 (mm) Power supply: AC100-110V Product weight: 7.5kg Ultrasonic frequency: 4MHz, 7MHz, 10MHz Ultrasonic heat energy: 0.10～2.00J
