Diamond Peel microdermabrasion machine . Top of the line in the diamond series of machines. Paid K new. It has been in its original protective box sealed in plastic. No corrosion or mold damage. I have extra sterile crystals. I used sterile crystals as I used the machine in a medical environment. I have a few extra disposable tips. I have used it recently and it works perfectly. I'm asking 0. I sold several of these machines to esthetic schools in California when I was in sales.
