Core Set 2021 Booster Box
Each Booster Box contains 36 boosters (540 cards) plus a Buy-a-Box promo card. For M21, this card is Rin and Seri, Inseparable.
Booster boxes are great for everyone who likes to get a bunch of cards from the newest set or if you want to draft at home. Buying a booster box is usually cheaper then just buying 36 boosters separately.
