Recommendations for smudge-proof and easy-to-apply eyeliners!!

I first came across this product by chance, so I stocked up on several and have been using them ever since! It's the Forencos Tattoo Eyeliner.

The thin brush shape makes it easy to draw with and control the amount of product. The only downside is that it definitely doesn't smudge easily, so it's difficult to correct if you don't draw it right the first time! Aside from that, I am very satisfied with the product. If you are looking for an eyeliner that doesn't smudge easily, I highly recommend this one!!
