About Arthur’s Roundup Box

Arthur’s Roundup Box is a baseball card experience built for collectors who love opening packs. Each ride brings together a curated mix of factory-sealed packs from different years, sets, and styles, along with a printed Guide Book and supplies for your pulls.

We choose the packs. The rest is yours to discover.

What’s Inside

Every monthly Roundup Box includes:

  • Factory-sealed baseball card packs
  • A printed Guide Book with pack details, key rookies, notable cards, and collector notes
  • A 100-count pack of penny sleeves
  • A card storage box
  • A small ballpark-inspired treat, such as sunflower seeds or gum

Choose the amount you want to rip: Copper has 5 packs, Silver has 10, and Gold has 15. Each tier is built for variety, with no duplicate packs within your box. Pack lineups change from ride to ride.

How We Build Each Ride

Some rides lean into modern releases or prospects. Others revisit older sets, familiar favorites, or products collectors might not normally open together. We choose packs with one goal in mind: keep the rip fun and give every tier a thoughtful mix.

Every pack arrives sealed exactly as it left the manufacturer. We don’t open packs, reseal cards, or fill boxes with loose singles.

No repacks. No filler. No funny business.

The Surprise and the Lineup Reveal

We keep the pack lineup under wraps while the initial boxes ship so riders can discover it for themselves. After boxes have had time to arrive, we publish the full lineup for everyone to see.

You can revisit past rides through our lineup reveals and digital Guide Books. They show exactly which packs went into each ride and offer more context on the sets and cards inside.

Like any factory-sealed pack, individual pulls depend on the cards the manufacturer packed. Autographs, rare parallels, and other hits are never guaranteed.

Ride Your Way

During the monthly season, you can purchase a Roundup Box once or join the Roundup Club for automatic rides at subscription pricing. The Club page explains the tiers, billing, and how to manage your subscription.

October Ride #11 is the final monthly baseball Roundup Box of 2026. Its order window has closed, and the pack lineup will be revealed October 9. Monthly subscriptions are paused after this ride. Billing is scheduled to resume in January for the February 2027 ride unless you cancel.

We’re also planning smaller, limited Roundup Box releases during the break. These will be optional one-time purchases, separate from monthly subscriptions. Subscribers will get first access before each release opens to everyone, with no automatic charge for these extra boxes.
