OPI x M&M's Sweeten Your Mani Collection

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.

The twelve shades

Six cremes and six shimmers. The kit packaging marks each one C for creme and S for shimmer. Each shade carries an OPI code, HPT for the Intelli-Gel bottle and HRT for the Nail Lacquer:

• HPT01 / HRT01 Feeling Mmmerry - golden yellow shimmer (S)
• HPT02 / HRT02 Melt In Your Mani - true red creme (C)
• HPT03 / HRT03 All Treat, No Trick - warm orange creme (C)
• HPT04 / HRT04 Choco-Lotta Cheer - milk chocolate bronze shimmer (S)
• HPT05 / HRT05 Crack Me Up - candy blue creme (C)
• HPT06 / HRT06 Merry Crunch-Mas - pine green shimmer (S)
• HPT07 / HRT07 Peanut Butter Me Up - chocolate brown shimmer (S)
• HPT08 / HRT08 Deck The Shells - silver foil shimmer (S)
• HPT09 / HRT09 OPI Want Them All - candy pink creme (C)
• HPT10 / HRT10 What A Tree-T - deep pine teal creme (C)
• HPT11 / HRT11 White Choco-Hot - white chocolate creme (C)
• HPT12 / HRT12 Red-iculously Sweet - cherry red shimmer (S)

How the collection is packed

OPI splits the GelColor side into two add-on kits of six. Intelli-Gel Kit #1 holds Feeling Mmmerry, Melt In Your Mani, All Treat No Trick, Choco-Lotta Cheer, Crack Me Up and Merry Crunch-Mas.

Intelli-Gel 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 Intelli-Gel set, and the Gel and Lacquer duo set adds the twelve matching lacquers.

Each kit also carries a blank nail palette with a chain and a GelColor table top instruction card, as printed on the box, so the shades can be swatched on the desk in front of the client.

The Nail Lacquer side is sold as a set of twelve 0.5 oz bottles, one per shade. The counter display stand is not part of it.

Every shade is also sold on its own: as a single Intelli-Gel bottle, a single Nail Lacquer, or a gel and lacquer duo of the same name. Search the shade code, for example HPT05 for the Crack Me Up gel or HRT05 for its lacquer, to find the exact bottle.

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 set for the shelf.

Applying the GelColor shades

1. Prep and dehydrate the natural nail, then apply the OPI base coat and cure.
2. Apply a thin first coat of colour and cure for 30 seconds under an LED lamp.
3. 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.
4. 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.
