Love these! (18 November 2008)
I am currently using these for my christmas cards, and they're so great! The glitter is green, but when you look closely it subtly reflects other colors too, wich makes it look more "alive" on the page.
Also, they stick very well to the page, and because it's foam you can probably stick it on to non-flat surfaces as well.
They look much better in real life than on this picture!
