the bottle is tiny, but it's tiny because it is MUCH more concentrated. you'll get more color and more shimmer with each spritz with Smooch Spritz. it also will NOT warp your paper or your projects because it isn't "watery" like glimmer mist. think of it as an ink you can spray. it just depends on the look you are going for. Glimmer Mists are sheer and give a soft all over shimmer - but may warp your paper. Smooch is more opaque and you can spritz just a little to get a light coverage, or apply more for a heavier coverage.
i did a comparison of several "mist" type products on my blog:
Sprays, Spritzes and Mists - oh my!
i've also posted LOTS of Smooch projects on my Clearsnap Blog {link in siggie}. just click on "smooch spritz" in the list of categories on the sidebar and it will bring up all the projects that include Smooch Spritz.
There are different types of sprays for different types of uses, they all add shimmer, but aren't all the same!
Good luck and have fun!
