Precision Lip Defining Pencils from Chanel
(like the Edward Bess lipsticks and gloss) have a silicone base that sets. It also doesn’t melt like wax based pencils (almost every other brand uses these pencils with a similar base made in West Germany) after it’s been on your face at (98 degrees) for a few hours. It prevents the lip pencil from feathering into any lines that may be around your mouth. (my favorite color, by far is Nude)
