Product questions
What is the difference between Hobby and Jumbo for this release?
This listing is for the Jumbo Box. Leaf lists Jumbo at eight autographs, eight base cards, and one on-card signature per box, while the standard Hobby box is configured with four autographs, four base cards, and one on-card signature.
Are the on-card signature and autograph subjects guaranteed to be specific players?
No. The format includes one on-card signature per box, but specific players, legends, prospects, autograph combinations, and insert themes vary by box.
Are the highlighted young-star signatures guaranteed in every box?
No. Leaf states that selected young-star signatures land at roughly three to four per case, so those names are chase content rather than guaranteed box pulls.
If you want a 2026 Leaf Metal Baseball format with bigger autograph volume and an on-card chase built in, this Jumbo Box is ready for your next baseball break.
