A staple in any makeup brush lineup, the Ruby Kisses RMUB18 Lash, and Brow comb offers a two-in-one tool to lift, define, separate, and shape the lashes and brows. One side is a small, fine-tooth comb that will help de-clump mascara and break up natural lashes. Even use the comb for applying product to lashes or touching up a false lash application. The other side offers a soft-bristled brush that is thin enough to fluff up and outline the perfect brow shape.
