What Is Arthur’s Roundup Box?

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.

Each box is built using packs pulled from freshly opened boxes across hobby and retail formats. Pack lineups change monthly, and boxes are designed to give collectors variety across sets and eras — without the cost of a full hobby box.

Boxes ship during the first week of each month, and orders must be placed by the 25th to receive the upcoming month’s box.

Is the Roundup Box a Mystery Box?

No.

Arthur’s Roundup Box is not a mystery box. All packs are factory sealed, and pack lineups are announced ahead of time. No repacked, resealed, or loose cards are ever used.

The only randomness comes from:

  • Which sealed packs you receive

  • The cards inside those packs, based on manufacturer odds

Are Autographs or Big Hits Guaranteed?

No.

Just like opening sealed packs yourself, autographs, relics, inserts, and parallels are not guaranteed. Any hits are pulled naturally based on the odds of the packs included.

Transparency matters — and expectations should be clear.

Who Is the Roundup Box For?

Arthur’s Roundup Box is a good fit for collectors who:

  • Enjoy ripping packs for fun

  • Like variety across sets and years

  • Want a hobby-style experience without paying hobby box prices

  • Prefer factory-sealed products with clear expectations

It may not be the right fit if you are only chasing guaranteed hits.

## Access to Hobby Packs at a Lower Price Point

One of the goals of the Roundup Box is to give collectors access to **hobby-format packs** without requiring the purchase of a full hobby box.

By curating packs from freshly opened hobby and retail boxes, some monthly lineups may include a majority of hobby packs within a single Roundup Box. This approach allows collectors to experience hobby products at a more accessible price point, while still maintaining variety across sets and eras.

Pack formats and ratios vary by month.

How the Monthly Subscription Works

  1. Orders placed by the 25th are included in the upcoming month’s box

  2. Pack lineups are curated and boxes are assembled

  3. Boxes ship during the first week of the month

  4. Subscriptions renew monthly and can be managed anytime
