Designed for Asian eyelashes, the original "Four-Heart Square Brush Head" can accurately apply mascara to each eyelash, even if the small eyelashes at the end are not missed. The "High Order Thermal Sense Technology" can quickly form a protective film on the mascara brush to resist the attack of sweat and oil. The 24-hour long-lasting is not smudged, so it can be easily removed with warm water.
