DND DC Duo: gel and lacquer under one number
A DC Duo is DND's matched pair, a gel polish and a lacquer sold together under a single number. DND DC Duo 031 Milky Blue, 319 Coffee Bean, 321 Goodie Bag and 888 Extreme Black all follow that pattern, so the number on the box is the number your client points at on the color wall.
What having both bottles lets you do
One number covers two services. The gel goes on the hands and cures under an LED or UV lamp at the cure time DND specifies, while the lacquer from the same set handles a pedicure or sells at the counter to a client who wants to touch up between visits. Buying the pair also means you track one code instead of two bottles on two order lines, which is one less way for your gel wall and your lacquer wall to drift apart over a year of reordering.
How this differs from our other DND pages
This collection is DC Duos only. The broader DND catalog covers the brand's other lines, while DND trio sets add a dip powder to the set for salons that offer dip alongside gel. If you are weighing two-piece against three-piece sets across brands, trio and duo sets is the page to compare on, and DND dip is the powder side of the brand on its own. Orders ship in 1-2 business days, and there is free shipping on orders over $150 within the 48 contiguous states.
