Slide off the battery cover and insert 2AAA batteries. Push on/off button up to turn on. The green light will illuminate. The red silicon pad changes color to clear (around 10-15seconds) when the curler is ready for use. Place eyelashes on silicon pads, push slide lever upward until pads stop. Hold on eyelashes for 15 seconds. Release and repeat on the other eyelash until desired look is achieved. When finished, slide on/off button downward to the off position. The light will go off. For the best, long lasting results, we recommend a coat of mascara after curling.
