Collection: Roundup Box

Each Roundup Box delivers a curated mix of baseball card packs from across the hobby, with multiple tiers available for different collecting styles.

Monthly lineups may include modern releases, prospect-focused products, throwback packs, chrome sets, flagship products, and surprise bonus inserts, all selected to create a hobby-shop ripping experience delivered straight to your door.

No repacks. No searched packs. No loose mystery filler. Just factory-sealed baseball card packs, clear monthly reveals, and a collector-run approach from Arthur’s Cards & Collectibles.

Whether you’re joining for one month or subscribing for the next ride, the Roundup Box is made for baseball card collectors who enjoy the chase, the variety, and the fun of opening something new.
