Releases 3/18!

2026 Topps Heritage Baseball Mega Box is a sealed box made for set builders who want 1977-style baseball trading cards with retail-only parallel chase.

Box configuration:

• 17 packs per box

What you’re chasing:

• Mega Box–exclusive Base Red parallels

• Mega Box–exclusive Chrome Silver Sparkle parallels

• Short prints and variations that add extra chase while you build the set
