New Stila Lip Rouge Liquid Lip Stain Pencil. This is a new Revolutionary Stila lip rouge. These 'pens' are the makeup incarnation of a felt-tipped magic marker. Complete with a sculpted nib, the pens line and fill in your lips effortlessly for long-lasting color. Just turn the pen upside down to get the color. This is a super thin, precise point applicator which has a flat side end for applicator. Although thin it applies beautifully and allows you to line your lips as well if you want.
