What’s Inside the Roundup Box
Arthur’s Roundup Box is designed to deliver the excitement of opening packs at your local card shop — with the care, transparency, and value collectors expect.
Each month features a rotating lineup of factory-sealed baseball card packs, paired with thoughtful extras to help protect, enjoy, and understand your pulls.
Factory-Sealed Baseball Card Packs
Every Roundup Box includes a curated mix of factory-sealed packs sourced from freshly opened boxes across hobby and retail formats.
Pack lineups rotate monthly and may include:
Modern releases and select past products
Hobby, jumbo, mega, blaster, or retail formats
Packs from trusted manufacturers such as Topps, Panini, and Upper Deck
All packs are unsearched and factory sealed — no repacks, no filler, no gimmicks.
Boxes will also be sealed with an official Arthur’s holographic sticker corresponding to your selected tier (Copper, Silver, Gold). These are to verify authenticity and confirm that all contents remain unopened until they reach you.
Roundup Box Guide Book
Each month includes a physical copy of the Roundup Box Guide Book, created to enhance the opening experience.
Guide Books highlight:
That month’s pack lineup
Key rookies and notable players
Popular inserts, parallels, and chase cards
Digital Access:

Collector Supplies & Extras
To make sure you’re ready the moment you start ripping packs, every Roundup Box also includes:
A 100-count pack of soft penny sleeves
Perfect for immediately protecting your favorite cards.
A sturdy card storage box
Designed to store, organize, and protect your new cards right out of the box.
A small ballpark-inspired treat
A pack of sunflower seeds or classic bubble gum — a nostalgic nod to baseball and the hobby’s roots. *Snack item may vary based on availability.
Randomization & Monthly Variety
Pack selection, extras, and any bonus items are randomly distributed across all boxes.
There are no guaranteed hits, but packs are sourced from manufacturer boxes that may contain autographs, relics, parallels, or other inserts based on published odds.
Every month brings a new mix — keeping the experience fresh while staying transparent.
