What is Arthur’s Roundup Box?

Arthur’s Roundup Box is a collector-run monthly baseball card subscription box featuring a curated mix of factory-sealed baseball card packs sourced from freshly opened boxes.

Is Arthur’s Roundup Box a mystery box?

Not in the traditional sense. While the monthly pack lineup is kept a surprise for subscribers until reveal day, every Roundup Box is intentionally curated with factory-sealed packs from across eras — no repacks, filler, or previously opened products. Full lineups are revealed publicly on the second Friday of each month when limited extra boxes become available.

Are the packs factory sealed?

Yes. All packs included in Arthur’s Roundup Box are factory sealed and pulled from freshly opened boxes.

Are hits guaranteed in the Roundup Box?

No. Autographs, relics, inserts, and parallels are not guaranteed and are pulled based on manufacturer odds.

When do Roundup Boxes ship?

Roundup Boxes ship during the first week of each month.

Subscribers always come first.

Bonus extras may include:

Built by Collectors

Arthur’s Cards & Collectibles is collector-run. We source packs we’d actually open, seal boxes the way we’d want them sealed, and share lineups openly once the surprise window passes.

Every Roundup Box reflects how we believe collecting should be: honest, fun, and fair.

We also publish monthly Roundup Box Guide Books so collectors can explore pack lineups, key rookies, chase cards, and set notes as they open each pack.
