Whether you do your own nails or have it done, you should own at least one of Mavala Colorfix. This is possibily the best top coat ever. Yes, even better than OPI’s.
Mavala Colorfix is a clear top enamel that dries to a hard elastic glaze and provides nail color with an extra protective armor against chipping and peeling. Reinforced with acryl, Colorfix contributes a brilliant sheen to nail colour and “fixes” it, forming an extra protective shield against flaking. In fact, I find that it can fix uneven nail coating and is even able to cover up little bubbles.
