2025/26 Topps Basketball Mega Box 4x Lot

The 2025-26 Topps Chrome Basketball Mega Box 4x Lot is a bundle of four sealed Mega boxes from Topps Chrome's return to fully licensed NBA basketball trading cards — the brand's first licensed standalone basketball release since 2008-09 — built around a 299-card base set featuring the NBA's top rookies, star veterans, and iconic legends with Chrome technology and an extensive rainbow of Refractor parallels. Each individual Mega box contains seven packs of eight cards per pack, with guaranteed contents including two base card Refractor parallels, one Prism Refractor, two RayWave Refractors, ten X-Fractor parallels exclusive to the Mega format, and three insert cards. Key autograph chases across the product include rookie signers Cooper Flagg, Dylan Harper, Ace Bailey, and Cedric Coward alongside veterans Victor Wembanyama, LeBron James, Stephen Curry, and Chet Holmgren, and Hall of Famers Allen Iverson, Magic Johnson, and Dirk Nowitzki. The 4x Lot provides four complete Mega box openings in a single purchase, maximizing the X-Fractor parallel pulls and insert content exclusive to the Mega format across all four boxes while significantly increasing the statistical probability of hitting rare inserts and numbered parallels.

Released August 26, 2026 at $400 retail for the four-box lot through hobby and general retail channels globally with individual Mega boxes retailing at $84.99 each.
