OPI x M&M'S Holiday Advent Calendar 2026 by the numbers
How each one is countedEvery figure is computed from the record at build time and set against the median of the same season and the same kind of contents. Door price is the price on the box over its doors; the value multiple is what the contents come to at retail over that price; full size is the retailer’s own marking. Where the record cannot support a figure, the page leaves it out rather than guessing.The definitions, one by one →Each figure against the median of this season's beauty shelf — 202 calendars. Green is the better side of the median, red the worse; the median is printed so you can disagree.

Our OPI x M&M'S Holiday Advent Calendar 2026 review
Our verdict
Twelve mini OPI lacquers in a box that leans hard on the M&M'S joke, and the shades back it up with a proper spread of candy brights and chocolate browns. It is only polish, though, and only twelve days of it.
Reviewed by Viktoria · 2026 season · How we review
What works
- Twelve shades, all from the M&M'S holiday collection
- A real colour range: brights, browns, a white and a red
- OPI's regular lacquer, not a sample formula
What does not
- Twelve doors, not 24
- Mini bottles only; nothing else in the box
