If you don't know what a nail polish jelly is, it's a type of nail polish that has a finish of something similar to a gel-manicure. It looks "jelly" and is transparent depending on the amount of layers you apply. Think of it as jello on your nails. "Shell-O" was too sheer, and so I wore 4 layers of the polish in order to build up the opacity.
I ended up taking this polish off because it began chipping very badly the day I took the picture above. I've never seen nail polish like this chip so easily before, which makes this polish a disappointment. I do not recommend this polish!
