In terms of application, I just swipe this over my lid and blend with my finger. This works really well and the product is smooth enough that it blends really easily, leaving a sort of duo-tone darker colour in the crease - if you have MAC Woodwinked you'll know what I mean!
The lasting power of this is really good - I'd say I get a good 6-8 hours out of it before creasing. This is along with the use of a base such as MAC Bare Study underneath. I do like to set the crease with a powder eyeshadow. I use both purples or browns with this - I've found both work just as well as the eyeshadow stick is such a versatile colour.
They're a bargain at only £6.90 - a fraction of the price of a By Terry one! You can buy them online here.
