Nitro dip powders are numbered rather than named, as in NITRO 026, NITRO 080 and NITRO 278, and a number of listings also carry an SNS number in the title, such as NITRO 080 Dip 2 oz - SNS 331. If your shade book was built around that other numbering, the cross-reference gives you a starting point for finding a comparable jar instead of swatching the whole wall again. The color jars listed here are 2 oz.
Working from a numbered range
A numbered range reorders cleanly and browses badly. One way around that is a physical swatch stick: paint one tip per shade, write the Nitro number on the back, and add the SNS number underneath where the listing shows one. Clients pick from the stick, you type the number, and nobody is hunting for a color by description. Keep the stick current as jars come in, and pull the swatches for shades you stop carrying so you are never selling a color you cannot take off the shelf.
Length, not just color
NITRO Dip Extension Foundation is a 2 oz powder made to build structure rather than add color, so a dip service on this line does not have to stop at overlays. If you are adding length, nail tips and adhesive are listed separately, and shaping afterwards comes down to what is in your file drawer.
Before you commit shelf space
Committing to a dip line means committing shelf space to it, so it is worth checking what a range covers before the first order goes in. If you are still deciding between brands, our dip powder page collects them in one place so you can compare jar sizes and code systems before ordering. Orders ship in 1-2 business days, with standard transit of 2-5 business days after that, and there is free shipping on orders over $150 within the 48 contiguous states.
