Frequently asked questions
What is the OPI x M&M's Sweeten Your Mani collection?
It is OPI's Holiday 2026 collaboration with M&M'S: twelve limited-edition shades named after the candy, six cremes and six shimmers, in the 0.5 oz bottle. OPI released it in GelColor, Nail Lacquer and Infinite Shine.
How many shades are in the collection?
Twelve: Peanut Butter Me Up, Deck The Shells, OPI Want Them All, What A Tree-T, White Choco-Hot, Red-iculously Sweet, Feeling Mmmerry, Melt In Your Mani, All Treat No Trick, Choco-Lotta Cheer, Crack Me Up and Merry Crunch-Mas.
What is the difference between GelColor Kit #1 and Kit #2?
They are the two halves of the GelColor line-up. Kit #1 holds Feeling Mmmerry, Melt In Your Mani, All Treat No Trick, Choco-Lotta Cheer, Crack Me Up and Merry Crunch-Mas. Kit #2 holds Peanut Butter Me Up, Deck The Shells, OPI Want Them All, What A Tree-T, White Choco-Hot and Red-iculously Sweet. Take both, or the 12-colour set, for the whole collection.
What comes in each GelColor kit besides the polish?
Six 0.5 oz GelColor bottles, a Holiday 2026 palette label, a blank nail palette with a chain and a GelColor table-top instruction card.
What is in the Nail Lacquer display?
Twelve 0.5 oz Nail Lacquer bottles on the Holiday 2026 vac tray with wrap graphics, plus the Holiday 2026 palette label and a blank colour palette with chain.
How long does the GelColor wear?
OPI rates GelColor at up to three weeks of wear and shine. It cures in 30 seconds under an LED lamp and is removed by soaking off, not filing.
Do I need a lamp for the Nail Lacquer?
No. Nail Lacquer is the classic air-dry polish - base coat, two coats of colour, top coat, no curing. It is the version most clients buy to take home.
Will these shades come back next year?
No. Holiday collections are limited edition; once the season's stock is sold the shades are retired rather than restocked.
What is the OPI x M&M's Sweeten Your Mani collection?
Sweeten Your Mani is OPI's Holiday 2026 collaboration with M&M'S. Twelve limited-edition shades take their names and their colours from the candy: chocolate browns, a peanut butter shimmer, candy blue, pine green, and three reds that run from cherry shimmer to a flat holiday red.
OPI's line for it is "Sweeten your mani. Brighten your holiday." The shades ship in the standard 0.5 oz (15 mL) OPI bottle, in GelColor and in Nail Lacquer, so a salon can run the same holiday menu on the table and on the retail shelf.

How the collection is packed
OPI splits the GelColor side into two add-on kits of six. Kit #1 holds Feeling Mmmerry, Melt In Your Mani, All Treat No Trick, Choco-Lotta Cheer, Crack Me Up and Merry Crunch-Mas.
Kit #2 holds Peanut Butter Me Up, Deck The Shells, OPI Want Them All, What A Tree-T, White Choco-Hot and Red-iculously Sweet. Both halves together are sold as the 12 colour GelColor set.
Each kit also carries a Holiday 2026 palette label, a blank nail palette with a chain and a GelColor table top instruction card, so the shades can be swatched on the desk in front of the client.
The Nail Lacquer side comes as a counter display: twelve 0.5 oz lacquers on a printed Holiday 2026 vac tray with wrap graphics, plus the palette label and a blank colour palette with chain. It is built to sit on the retail counter rather than in a drawer.
GelColor or Nail Lacquer?
GelColor is the salon service colour: brushed on, cured under an LED lamp in 30 seconds, and worn for up to three weeks with the shine it had on day one. The bottles in this collection carry OPI's Intelli-Gel technology, as printed on the label.
Nail Lacquer is the classic air-dry polish: no lamp, a ProWide brush, high-gloss and chip-resistant, and it is what most clients buy to take home. OPI also released the collection in Infinite Shine, its gel-effect lacquer that wears up to eleven days without curing.
A salon that wants a matching service and retail wall takes the GelColor 12-colour set for the table and the Nail Lacquer display for the counter.
Applying the GelColor shades
- Prep and dehydrate the natural nail, then apply the OPI base coat and cure.
- Apply a thin first coat of colour and cure for 30 seconds under an LED lamp.
- Apply the second coat and cure. The shimmers - Deck The Shells, Red-iculously Sweet, Peanut Butter Me Up, Choco-Lotta Cheer, Feeling Mmmerry and Merry Crunch-Mas - build their sparkle on the second coat.
- Finish with the OPI top coat, cure, and wipe the tacky layer if the top coat calls for it.
Buying for the holiday season
These are limited-edition shades: OPI retires a holiday collection once the season's stock is gone, so the twelve names above are not restocked the following year.
Salons that run a holiday menu usually take the full twelve rather than a half kit, because the six brights and the six chocolates read as two different menus on the nail. The rest of the range sits in the OPI collection.
