Blinc's Lash Extension Tubing Mascara is CLEAN, VEGAN & buildable. It creates ultra-longwearing, striking length & extreme definition for a lash extensions effect in a semi-matte finish. Infused with Biotin, Shea Butter & Castor Seed Oil, it also provides nourishment and treatment for your lashes. Its 1KTech molded brush is cone-shaped with QuickApply bristles for effortless application. Our pioneering tubing technology forms tiny water-resistant "tubes" around your lashes, rather than painting them like conventional mascaras. Once applied, the tiny tubes bind to your lashes and can't run, smudge, clump, or flake, even if you sweat, cry, rub your eyes or have oily skin.
