OPI has launched a limited-edition holiday collection built around M&M's, with 12 Nail Lacquer shades available across four of the brand's formulas plus press-ons and gift sets.

The OPI x M&M's Sweeten Your Mani collection went on sale today. It offers classic crème and shimmer shades in four formats: Nail Lacquer, the polish classic; GelColor, the long-wear in-salon gel; Infinite Shine, which delivers gel-like wear with regular polish application; and RapiDry, a one-coat manicure that dries in 60 seconds.

Why the pairing is personal for OPI's cofounder

OPI cofounder Suzi Weiss-Fischmann has a direct link to the candy. She grew up in Hungary waiting eagerly for care packages of M&M's from her aunt, and her mother would ration out just a few a day. Holding those vibrant colors in her hand is a "core memory," she says. She calls the collaboration the "sweetest pairing" to cap OPI's 45th anniversary year.

The deal puts Mars-owned M&M's — one of the most recognizable candy brands in the world — next to a nail brand marking nearly half a century in professional color.

What's in the gifting lineup?

The collection's mini packs are structured for holiday gifting at three price-accessible sizes:

• A 12-piece set containing all 12 holiday Nail Lacquer shades in an advent-style box
• A six-piece set with six of the holiday shades
• A four-piece set pairing two holiday shades with two OPI classics: Bubble Bath and Big Apple Red

The press-on range adds six Sticking Point Instant No Glue designs. They include two monochrome options, some with M&M's-colored French tips and others with M&M's-inspired circles.

What does the launch signal?

The collection arrives months before the festive season, a timeline OPI appears to expect shoppers to ignore — the brand itself suggests wearing favorite shades well ahead of the holidays, noting that, like a bag of M&M's, they're hard to resist.

For OPI, the M&M's tie-in closes a milestone year: 45 years in business, sealed with a collaboration its cofounder frames as the "sweetest pairing" of her career's anniversary calendar.
