Topps NBA Signature Class Jumbo Box
2025-26 Topps Signature Class Basketball Jumbo Box – NBA Debut Edition
Experience the official debut of Topps’ NBA trading cards with the 2025-26 Topps Signature Class Basketball Jumbo Box. This sealed Jumbo Box marks a new chapter for NBA trading cards, offering collectors and enthusiasts access to exclusive autographs, rookies, and ultra-rare chase cards — all under the NBA's official license and with Topps's signature premium finish.
Contents and format of the Jumbo Box
The Jumbo Box format is characterized by larger packs and more hits than classic hobby or retail editions. Each box contains:
- 4 packs per box
- 10 cards per pack (40 cards total)
- An average of 4 autographs per box
All cards are English-language and arrive factory-sealed. You have access to the full base set of 150 cards, of which 50 are rookies. Each base card is available in both Paper and Chrome, and there is a wide range of parallels and numbered editions — including SuperFractor 1/1 and Foilfractor 1/1.
Chase cards, rookies and autographs
The collecting potential in this Jumbo Box is significant, especially with a focus on the 2025 rookie class. You can chase cards of prospects like Cooper Flagg, Dylan Harper, Kon Knueppel and Ace Bailey. The box also offers autographs and parallels from both active NBA stars and legends — names like LeBron James, Stephen Curry and Victor Wembanyama are among the most sought after.
Among the rarest chase cards you’ll find the ultra-rare Monarchs of the Game and Leviathans case hits, which appear only in Hobby and Jumbo formats. The autograph content ranges widely, including Rookie Class, Veteran Class, Chrome Autos, Dual/Triple Autos, and named inserts like Crystal Clear and Legends of Their Class.
Official NBA license and premium finish
All cards in the Signature Class series are officially NBA-licensed with authentic team logos and player jerseys. Topps's use of Chrome technology and a wide selection of parallels ensures a premium collecting experience, whether you’re chasing rookies, legends or the rarest inserts.
Storage and accessories for your cards
To protect your autographs, parallels and rare inserts, we recommend checking out our range of accessories for storage and protection. Here you’ll find sleeves, top loaders and boxes that fit both Paper and Chrome cards perfectly.
