The eyeliner pencil is the best one to use in the waterline of your eye.
The GEL EYELINER that I use is from Bobby Brown. I have the colours sepia ink & black ink, these ones are very long lasting and I apply it with a ultra fine brush. I don't normally like gel based eyeliners because I find they apply a little bit tricky, and i didn't have a very nice experience with other gel eyeliners. When I apply this one I only have to dip the brush in the gel eyeliner once, draw the line.., and it's done! I really like it!
The LIQUID EYELINER is my favorite! I always use L'oreal Paris Super Liner carbon gloss, the application is very easy.
The applicator design is super thin, flexible, and the product comes out evenly.
I find that it stays a long time and doesn't smudge or run.
And it is an inexpensive product.
