Nitro Duo: dip and dap powder with the gel polish to match
A Nitro Duo is a two-piece set, the dip and dap powder plus the gel polish made to the same shade number. This collection holds 133 of them, catalogued by number rather than by shade name: NITRO DUO 044, 057, 065, 113 and on through the range. If your salon runs both dip sets and gel sets, buying the pairs instead of two separate lines is what keeps one number looking like one color across both services.
Why the number is the whole system
A three-digit number writes onto a service ticket without ambiguity. Record the Nitro number at the end of a visit and the next appointment starts from a known quantity, whether the client comes back for dip or for gel. It makes reordering mechanical too: read the numbers off the display, order those numbers, done. Keep the two halves of a duo shelved together so a technician is never matching powder to gel by eye at the station, and label the shelf with the number rather than a description.
Where duos sit against the other set formats
Duos are the two-piece option. Three-piece sets that add lacquer are on trios, and duo and trio sets across brands are grouped on trio and duo. If you only need powder and already have your color coats covered, the standalone dip range is on dip powder, while gel-and-lacquer pairings are on gel and lacquer. Gel polish needs a curing unit, and those are on the nail lamp page. Everything here is priced for salons and technicians buying at wholesale quantities, orders leave in one to two business days, and there is free shipping on orders over $150 within the 48 contiguous states.
