NOTPOLISH Duo: two pieces under one shade code
Every listing here is a NOTPOLISH Duo - a two-piece set sold under one shade code, such as OG02 White, OG03 Black, OG101 Milky White or OG102 Nude Panther. Product types on this page span gel polish, duo polish and acrylic dip, so the two pieces are not the same combination in every listing. Open the product page and confirm which two formats a given code includes before you order it for a station.
Duo or trio
A duo is the lighter commitment. You get a shade in more than one format without buying a third piece for every color on the wall, which suits shades you want available for two services rather than all of them. That makes duos a reasonable way to widen a wall with more colors instead of deepening every color you already carry. Where a shade has to cover every service on your menu, a three-piece set is the better fit.
Where duos sit next to the rest of the line
For the same shade carried across three formats, compare the duo and trio sets; the powders, step liquids, top coat and accessories sit under NOTPOLISH. For matched pairs from other brands, see gel and lacquer, and nail color when a client request only needs a single bottle. Orders ship in 1-2 business days, with free shipping on orders over $150 within the 48 contiguous states.
