Sugar Rim is a matte glitter in a clear base, and was super easy to apply. I love the mix of colors in this glitter. There's black, red, pastel blue and a pale yellow. There's also some metallic silver shards mixed in, which honestly, I still can't decide if I like or not. There's not a ton of silver pieces in the glitter mix, so they don't overpower the polish, but there's a small part of me that thinks I'd love the glitter so much more if they hadn't been added at all.
Shards and all, I really liked the way the glitter looked over this blue base. I used three coats of OPI Ogre-The-Top Blue. But I'd also like to do some experimenting on a nail wheel to test out some other colors to use as a base for Sugar Rim. I can see this working really well over quite a few different colors!
