Stay sharp! Smashbox Always Sharp Waterproof Khl Liner glides on smoothly and self-sharpens every time the cap is removed. Inspired by professionals who sharpen before every use on set, it gives the perfect tip for a precise line every time. The khl liner can also be used on the inner eye rim for an even more intense look and the nonflaking formula mimics the precision of a liquid liner in foolproof pencil form.
