What is the Roundup Box?

A monthly baseball card box built by collectors — not corporations.

Each month features a new lineup of factory-sealed packs pulled from hobby, retail, and exclusive boxes — designed to deliver the full rip experience without the cost of buying full boxes.

No repacks. No filler. Just packs we’d actually want to open ourselves.
