ColourPop Tulle Ultra Matte Liquid Lipstick ($6.00 for 0.11 fl. oz.) is a medium-dark, neutral-to-warm plum-red with a matte finish. It had fairly coverage that went on evenly and smoothly without pulling into lip lines or emphasizing them too much. It wasn't too thin, but it wasn't thick or goopy, so dry down time was a little faster than average but I had enough time to apply to the top and bottom without getting streaks. This shade lasted for twelve hours with minimal fading and what fading there was fairly even. It had minimal transfer until after I ate, and then it seemed to transfer more noticeably but blotting once or twice post-meal should help bring it back down to minimal transfer. For me, I noticed my lips feeling a little dry after six and a half hours of wear, and it was getting painfully dry at the eight-hour mark.
