I LOVE IT!!!! Sally Hansen's 2290 Has Super Shine Top Coat makes your nails super shiny!!! I used it on a very matte nail color, because I didn't want matte. It transforms a plain matte color to a super shiny color. Excellent!!! In the light, or sun, you can really see it shine. It's extremely shiny, On Mighty Gadget Kleancolor Complete Matte Metallic Set with Bonus Madly Matte, it makes it super Metallic in the sun and sparkly, otherwise, it would still be plain matte. If you have a matte or dull nail color, use Sally Hansen 2290 Has Super Shine Top Coat to make it shine.
