MAC Entre a Mi Mundo Lip Pencil ($17.50 for 0.05 oz.) is a light-medium brown with moderate, warm undertones and a matte finish. It had nearly opaque pigmentation in a single stroke, which applied evenly across my skin and could be layered without bunching up. The texture was firm with some tugging, but it wasn't painful to use, though it is more comfortable to use to line around the edge of lips rather than to fill in. I'd recommend holding it at a slight slant and using the edge to fill in, which was fairly comfortable.
In the past, MAC lip pencils have worn like iron--six hours or longer--and are lightly drying to non-drying on their own. I've swatched an unusually high number of lip products in the last couple of weeks, and my lips just were not in a state where I could handle testing this shade specifically for longevity, which is why it's a brief review.
