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. While we do keep the lineup secret during initial shipments, this is to keep the monthly surprise which our subscribers have grown to love. Each box contains a new pack lineup with no two months ever being the same. In addition, each lineup is purposely curated to provide value, fun, and variety from prior months and expand your collection as a whole. We don't rely on "chase" type promotions where we place something valuable in a couple boxes and then fill the rest with worthless junk. We're not saying you can't pull anything valuable. We're just saying that our box is different because we seek to maximize collector value in every box by picking packs that are affordable relative to their hit chances and the overall market. And most importantly, we build boxes that collectors enjoy ripping. No repacks, resealed, or loose cards are ever used.

 

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

Providing Access to Hobby Packs at a Lower Price Point

While pack formats and ratios vary by month, our boxes generally contain mostly hobby packs with a few retail packs mixed in. This ensures our collectors get maximum value and higher chances of pulling quality hits in each box. 

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

What if I Don't Feel Comfortable Subscribing?

No problem! We also offer each month's box as a one-time purchase during the subscription window.

What if I Don't Like Surprises? 

You may get a second chance to purchase after the subscription/pre-order window closes! After the 25th deadline, orders are closed for roughly 2 weeks until our Monthly Lineup Reveal on the second Friday of the month. We then release any remaining boxes (if available) for sale in our Roundup Box Archives available as a one-time purchase. Be sure to check our website or watch for an announcement on Instagram (@arthurscollectibles) for the lineup reveal and extra box drop. 

Note: We purchase sealed boxes specifically for each month's roundup. This means that we are only able to make a limited amount of Roundup Boxes. Extra boxes may or may not be available depending on the amount of subscription/pre-orders received.
