Topcoat is highly recommended for maximum shine and color impact.
Opacity can be achieved in 2 coats.
All Tonic nail polishes are 15ml, 5 Free (which means free of the chemicals toluene, formaldehyde, dibutyl phthalate, camphor, and formaldehyde resin), cruelty free, and handmade by me in the US using quality cosmetic pigments, glitters, and bases. Because products are handmade in small batches it is possible for slight variations to occur. However I follow my recipes very closely to minimize differences as much as possible.
