I bought this to tight line my top lash line. Ive been using the tony moly gel liner but having to clean brush every week can be annoying so wanted to try out a pencil liner. This does slightly smudge on my outer corner by the end of the day and the formula isn’t the creamiest so can be uncomfortable to use. I will use it in a rush but I don’t think this replaces the durability and ease of a pot gel liner.
