I purchased this for practicing at-home esthetics, but I'm selling it because I've decided to get a different machine. This is a multi-functional slimming machine, perfect for body care♡ Even when you're too busy to go to an esthetic salon!! You can do self-esthetic treatments at home whenever you like. Power and vacuum functions have been confirmed to be working. - Model Name: 3 IN 1 SLIMMING MACHINE - Functions: Slimming, Body Care - Accessories: 4 different heads Can be used on the face and body(^^) - Display: Digital Display - Head Type: Multi-functional heads (one is flat, others have multiple protrusions) Thank you for looking.
