To use, load your preferred lipstick onto the brush. Utilize the brush's rounded edge to effortlessly and symmetrically balance the two peaks, beginning with the cupid's bow. Apply the lipstick along the lip line to meet the cupid's bow, positioning the brush's long edge at the lip's corner. Repeat on both sides. The remaining lip should then be filled in and blotted together using the brush's flat side. The bottom lip line can then be easily and precisely defined with the brush's fine point. 32301 is the product code.
