DND Duo: gel and lacquer under one shade number
The listings on this page are DND Duos, meaning a gel polish and a regular lacquer matched to the same shade and sold together under one number, as in 430 Ferrari Red or 447 Black Licorice. That numbering is what makes the format practical for a salon. The shade cured at the station and the bottle that goes home are the same color, and a reorder comes down to a number rather than a description a supplier has to guess at.
Planning which duos to stock deep
One way to plan a duo wall is in layers. Start from your own ticket history and keep the most depth on the shades your services repeat, whether that is a red like 430 Ferrari Red, a black like 447 Black Licorice, or something else entirely. French work needs a dedicated white, and 473 French Tip is the duo named for that job; our French manicure ideas post shows sets that use one. A winter-leaning shade such as 448 Snow Flake is worth buying to a planned quantity against the season you book rather than by the case, and the winter nail art guide shows the kind of work it supports.
How duos differ from the other DND formats
If you want the three-piece format that adds a matching dip powder, start at DND trios. For dip powder on its own, use DND dip. Orders ship in 1-2 business days, with free shipping on orders over $150 within the 48 contiguous states.
