Dual-Purpose Lash Adhesive: It’s Duo’s dual-purposelash glue and liner in one! This double-tip lash serves as an adhesive when wet and settles with an intense black shade that can also work as youreyeliner.
Lash it Line it is the very best combo liner and eyelash adhesive in one. And I have tried a lot of them! It’s easy to line with because it has a very fine-tipped brush. Then you line a second coat and add the lashes. Works great, flexible and long lasting.
