Not a great shot, but I just wanted to show the cute little bag it came in!
Here's a better image, from the website. There's also a silver eye Crayon, called Moonshine, which I'm also tempted to get.
The Crayon can be used as an eyeliner or an all over shadow, I'm wearing it today and I'm very impressed. Sometimes 'crayon' products like this can be a bit too hard and drag when you apply them, but this is really soft so it goes on and blends very easily. The colour pay off is excellent and it gives a really gorgeous metallic sheen. It does crease a bit, but all products of this nature do tend to crease anyway, and it's lasted all day, so all in all, I'm really pleased with it.
Hope you can get an idea of the colour from this picture - I blended it a bit, but you can build it up to get a more intense, gold effect. It's lovely!
These are some of the other products I've got my eye on;
Glitter in Gilt, Eyeshadow Duo in Oopsy Daisy and Nails in The Big Easy
