These pencils have a very slight stickiness to them. They don't smudge, and don't feel odd or heavy when applied, but it does mean that they are a good base if you want to use a loose shimmer powder over them to line your eyes, and they last well on the waterline too, unless you wear contacts. If you wear contacts they still last well on the waterline, but unfortunately the pencil also gloms on to the surface of your contacts when you blink, and is a complete pain to get off them. (My optometrist would like me to add here that no-one should be wearing makeup on their waterline, least of all contact lens wearers. She's a bit of a killjoy though.) The texture is smooth, and easy to apply without tugging the skin.
The reason why I think the Crayon Blackstars are worth £19 each is that they wear like iron. You've got about 30 seconds to smudge them a bit, and after that, they do not budge. Not even the hottest, most humid day can fade these or make them smear. I can rub the swatches on my hand and they're still perfect. That does mean you need to use a decent makeup remover to take them off though. I love the colours I own too; Noir Velours is a true black, with no shimmer, and Bronze Ebene is a very flattering deep cool bronze with subtle shimmer.
