I find it one of the more difficult tasks of beauty to find a good liquid liner that won't result in black smudges on my cheeks from application or black mirror lines on my upper lid by the end of the day. I had tried a fair few liners from gel pots to liquid tips but didn't have much luck until I landed on the 

  Collection Extreme 24hr Felt Tip Liner. The application is easy because of it's felt-tip-like nib and it's got great staying power (for tips on how to make your liner stay put all day check out  this post). IT doesn't flake, fade, or transfer. A big thumbs up from me.

If you're more of a pencil liner fan, the  Avon Glimmerstick Eye Liner is a great one to try for a dramatic angled look (it's true black and highly pigmented) or smudged out for a softer, smokey look. It's a go-to liner for me because it stays put all day without transferring onto the upper lid or fading away. It's also a great one to try if you want to tight-line without transferring onto your lower rim. If you're as lazy (or, as I like to call it, low maintenance) as me, you'll love the fact that there's no sharpening involved. It uses a roll-up function that means it's always perfectly sharpened and ready to use. Score!

What are your holy grail liners? Do you prefer pencil, gel, or liquid?
