Knock Out, a line created by Mike Potter has brought a new twist to not only to the overly-trendy black nail but to the classic pink and ivory polish. Instead of glitter, shimmer or gloss, these polishes go on wet-dry matte and wear to a soft satin finish. If you would like a satin finish immediately, just buff over the polish. Karen O (shown here) is hearing the KO Flatte Black. The other shades are called: Calamine [Flatte Pink] and Powder [Flatte Ivory]. All three cost $22. See and add to cart.
