I used this at my esthetic salon, but I no longer need it, so I'm selling it. I used it for about 4 years. I have confirmed that it works and can be used without any problems. However, the main unit is quite noticeably dirty. In addition to the main unit, I will also include other accessories needed for the Jet Peel treatment. The main unit will be sent via household goods delivery, but the accessories will be sent separately by mail. Therefore, I would like to sell this to someone who can exchange addresses and other information via chat after purchase. The items for sale are as follows: Jet Peel treatment machine main unit Jet Peel handpiece (Triple Jet): 4 pieces JETS THAT DELIVER (Single Jet): 5 pieces Jet Care Clear: 50ml x 3 bottles (purchase date unknown) Jet Care Anti-Aging Complex: 50ml x 2 bottles (purchase date unknown) Jet Care Detox Water: 10 bottles (purchased November 2024) Other discontinued solutions: 50ml x 5 bottles (purchase date unknown) Renewal Complex: 50ml x 1 bottle (purchased October 2024) Jet Water: 1 (purchase date unknown, currently discontinued) Other discontinued solutions: 50ml x 5 bottles (purchase date unknown) Other discontinued solutions (unknown): 50ml x 1 bottle (purchase date unknown) It can be used without any problems, but please purchase only if you understand that it is a used item. If you have any questions, please contact me.
