2025 Topps Chrome Cosmic Baseball Hobby Box

2025 Topps Chrome Cosmic Baseball returns with a space-themed take on Chrome technology. Each hobby box holds 20 packs of 8 cards and includes one Nucleus Refractor card, built around a 200-card base set.

The 200-card base set covers leading stars of the game. Insert sets include Light Speed, Ultraviolet Beam, Extraterrestrial Talent and Star Clusters, with Supernova and Stellanova short print inserts focused on top players. The Planetary Pursuit insert chase is back for 2025. Its cards feature top players on a series of planets that grow harder to find the farther each planet sits from the Sun.
