【Authentic Product】 Purchased on April 28, 2025. While mascara can harden and become unusable even if some product remains, this product doesn't harden, allowing for long-term use. I bought several, but it seems like it will take a long time to use up one tube, so I'm selling it. I use it on my natural lashes. It's super easy and saves time on makeup because it combines morning lash treatment and mascara application in one step. It makes it look like you naturally have thick lashes. It might not be enough for those who want a dramatic look, but it doesn't clump at all and gives a glossy finish, resulting in an elegant look. People even tell me it looks better than when I apply regular mascara. The darkness is about the same as applying a clear black mascara. 【Product Description】 Contains over 20 types of serum ingredients, so it cares for your eyelashes while coating them effectively. The light application prevents clumping. Can be used on both natural lashes and eyelash extensions. ・For use with extensions: By coating the adhesive area of the glue, it prevents moisture, oil, and dirt from adhering, thus enhancing the durability of eyelash extensions. ・For use with lash perms (lash lifts): The black coating gives your lashes the appearance of clear black mascara. It doesn't clump at all and creates a natural and elegant impression. Unlike regular mascara, which can harden and become unusable even if some product remains, this product doesn't harden, allowing for long-term use. I bought several, but it seems like it will take a long time to use up one tube, so I'm selling it. ※ I am unable to respond due to being busy, so please refrain from price negotiations.
