2025–26 Topps Signature Class Basketball Mega Box

The 2025–26 Topps Signature Class Basketball Mega Box is the larger retail configuration of Topps’ fully NBA-licensed Signature Class release. It contains 80 cards and combines standard paper cards with Chrome variations, colorful parallels, rookies, short prints and randomly inserted autographs.

The 150-card base checklist includes 100 veterans and stars plus 50 rookies. Leading rookie targets include Cooper Flagg, Dylan Harper, Ace Bailey and Derik Queen, while veteran stars include Stephen Curry, LeBron James, Victor Wembanyama, Anthony Edwards and Shai Gilgeous-Alexander.

Each Mega Box delivers:

• 2 Mega-exclusive Chrome parallels

• 10 packs

• 8 cards per pack

• Opportunities for numbered parallels, short prints and autographs
  

The retail-exclusive Odyssey insert is one of the primary non-autograph chases. Other insert programs include High Fidelity, Pure, Unfazed, Roses, Aristocrat and Pressure Points.

Autograph possibilities include Chrome Autographs, Crystal Clear Autographs, Signature Blend, Shadow Scripts, Manuscripts, Eternal Marks, and scarce dual- or triple-signed cards. Unlike the Hobby Box, an autograph is not guaranteed in every Mega Box.
