If most eyeliners can be accurately referred to as eye "pencils", then Chanel’s Le Crayon Yeux would certainly be considered a rollerball. The line this product can draw along your lashes is far too smooth and elegant for a pencil to draw, making this more "Mont Blanc" than "Ticonderoga" any day. The other side of the eyeliner is a smudging tool, to help create that smoky eye you’re after. I highly recommend this product, and I should know… I own one in almost every color!
