2026 ONIT Gravity Baseball: Holoform, On-Card Autos and Two Retail Box Formats
ONIT’s national college baseball release introduces ION optichrome printing and a ten-player Holoform chase.
We update this release guide as verified product details develop.

Roch Cholowsky, Jaxon Willits, Ace Reese and Sawyer Strosnider are part of a 100-player college baseball set that crosses ten universities. The 2026 ONIT Gravity Baseball release brings those programs into one national product and introduces ONIT’s ION optichrome printing, with reflective card surfaces and on-card autographs. Official product details
Ten schools in one Gravity checklist
The roster covers Mississippi State, NC State, Oklahoma, Oklahoma State, TCU, Texas, Texas Tech, UCLA, Wake Forest and West Virginia. It is a mixed-school release, distinct from ONIT’s individual university team sets. The full checklist identifies the base, autograph and insert selections. Official checklist
The manufacturer’s card preview shows a Cholowsky signature design with a broad white signing panel, a Willits card against a red geometric field and an Ace Reese design with green framing. Reflective treatments and action cutouts connect the cards visually, while the different insert backgrounds keep the set from becoming one repeated layout.
Blaster and Mega boxes
| Format | Cards | Announced average contents | Exclusive parallels |
|---|---|---|---|
| Blaster — $24.97 | Five five-card packs; 25 total | Five parallels and two inserts | Base Green Mojo; Galaxy Purple |
| Mega — $49.99 | Six ten-card packs; 60 total | 12 parallels and six inserts, including one short-print insert | Base Teal; Base Pink; Galaxy Pink |
Blasters are offered through Walmart and Meijer; Mega boxes through Best Buy and selected hobby shops. ONIT specifies that every autograph is signed directly on the card. The announced box averages do not include a guaranteed autograph.
Holoform’s one-player-per-school selection
ONIT identifies Holoform as a case-hit insert, with ten subjects: Cholowsky, Strosnider, Reese, Logan Hughes, Willits, Kade Lewis, Kollin Ritchie, Gavin Kelly, Carson Tinney and Jacob Dudan. Each represents one of the ten universities, giving the insert a deliberately narrower scope than the 100-player roster.
Stardust, Hyperdrive and Galaxy add other designs, while the 7 Wonders checklist contains individually numbered /7 entries. The combination gives Gravity a national college-baseball identity built around school uniforms, reflective printing and several distinct insert selections.
