This pen-like eyelash curler has two levels of temperature (up to 70°C) which allows you to easily curl your lashes without pinching, tugging or pulling. Although the traditional eyelash curler has many advantages, it can't be denied that accidental pulling on the lashes while curling can cause to weakening of the roots.

Step 1: Pull out the battery cell from the aluminum pen and insert 1 *AAA battery. Slide the switch to ON. Wait until the green light illuminates. Step 2: Let the curler heat for about 20 seconds. Step 3: Place the heated comb directly under the eyelash line and gently lift eyelashes with curler against your eyelids. Hold the position for 8-10 seconds then continue until the desired look is achieved. Step 4: Once done, slide the button downward to the off position. Step 5: For optimum result, apply mascara after curling.
