Hello lashy lady. Here"s a real eye opener for the girl who would love to have the curl but has had it up to here with the crimping, pinching, and breaking of traditional hinged lash curlers. Now you can warm your way up to lashes that really get noticed. This sleek, safe and gentle heating wand delivers maximum curl where you want it without damaging your eyelashes. Beautiful. Instructions: 1. When the product is working, a green light should appear on the front. 2. If the light does not turn on, try turning the battery in the opposite direction as it could have just been placed backwards inside the curler. 3. It takes about 20 seconds for the heated eyelash curler to warm up as well. 4. This is a product to be used with mascara. It will not work without mascara and it will work better when the mascara is completely dry. 5. Hold the curler against the lid for about 8-10 seconds to activate the mascara and hold the curl after capturing the lash from underneath.
