Electronic hair remover uses an advanced technology - dry safe radio signals - directed to the root of the hair shaft. You can then pull the unwanted hair right out with the tweezer wand without skin pulling or pain. The specially designed tweezer wand works directly on the hair without ever touching your skin.Simply plug in the unit, hold the hair(s) to be plucked between the tweezer's attachment and wait 15-45 seconds (depends on short or long hair). The hair can than be pulled right out of the follicle with less or no pain! The signals (harmless to human body) penetrate deep into the root of the hair, killing it and helping to prevent the hair from growing back. 1.Size:L20.3xW10.7xH3.4cm 2.Weight:/about220g 3.Material:ABS 4.Accessories : Aadaptor Pad(big mid,small) Pad Cable Owners manual 5.Power supply:220V/50Hz 6.Watts:8W 7.High frequency:27.1Mhz
