Each card retains its original layout and has the 25th Anniversary logo in the bottom right corner of the card's artwork.
A pack of four cards was included in Happy Meals during the promotion, along with one of four novelty Pokémon items e.g. a sticker activity sheet, all contained within a cardboard envelope with a simple puzzle printed on the inside. Each card has a Non Holofoil and a Confetti Holofoil print, with one Confetti Holo included in each pack.
The McDonald's Collection 2021 is released in English, German, French, Italian, Spanish and Portuguese. All cards are available as both non-holo and Confetti Holofoil.
