Chanel Black Wood (945) Stylo Yeux Waterproof Long-Lasting Eyeliner ($33.00 for 0.01 oz.) is a deep, brown-tinted black with a semi-matte finish. It didn't have a true sheen, but it definitely didn't look flat and totally matte on my lash line either. It had opaque color coverage in a single stroke with a smooth, creamy texture with just enough slip to glide but set and stayed in place well. The majority of it was still intact after 12 hours of wear--very minimal thinning over time.

This new waterproof eyeliner formula delivers long-lasting definition with a twist of the wrist: Colour winds up when you need it, winds down when you don't. A built-in sharpener at the opposite end detaches for quick refreshes.
