Leaf Pro Set Metal Baseball Jumbo Box (2026)

Box Break:

• 🔹 8 Autographs per box
• 🔹 2 Red, White, and Blue Exclusive Parallels
• 🔹 10 Base Cards

The 2026 Leaf Pro Set Metal Baseball Jumbo Box brings the iconic designs of the late '80s and early '90s into the modern era with a high-shine metal finish. This Jumbo format is specifically built for collectors who prioritize volume and exclusivity, offering a significantly higher signature count than the standard Hobby release.

Each box is anchored by 8 total autographs, featuring a deep checklist of the game’s most anticipated young stars and "1st" card prospects. Collectors will also find the return of the legendary 1989 and 1990 Pro Set designs, reimagined in metal with various rare parallels.

The standout feature of the Jumbo format is the inclusion of exclusive Red, White, and Blue parallels. These fall two per box and are not available in any other configuration. With a checklist that includes top-tier names like Konnor Griffin, Travis Bazzana, and Leo De Vries, the 2026 Pro Set Metal Jumbo is the premier destination for serious prospectors looking to capitalize on high-grade "hit" potential.
