2025 Onit Baseball Signature Collection Blaster Box (Auto Guaranteed)

Before this year's MLB Draft even opened its doors, prospect collectors were already hunting for Roch Cholowsky — UCLA's elite shortstop and one of the most coveted 2026 MLB Draft prospects in the hobby. His on-card autograph, pulled from the 2025 ONIT Baseball Signature Collection Blaster Box, is the kind of pre-Draft get that defines a collection.

This officially licensed, team-specific release comes loaded for collectors right out of the gate. Each Blaster Box delivers 4 packs of 10 cards, with 4 parallels and 12 inserts per box — and the Blaster format carries a genuine shot at pulling a random autograph. Step up to the Platinum Box configuration and that auto is guaranteed. Every single signature in the set is on-card — no stickers, no shortcuts.

The autograph checklist reads like a scouting director's dream sheet. Alongside Cholowsky, collectors are hunting ink from Vahn Lackey (Georgia Tech), Ace Reese (Mississippi State), and a deep roster of top collegiate arms and bats across 23 programs — including programs from five of the eight 2025 College World Series teams. The defending national champion LSU Tigers are in the mix.

What you're hunting:

• On-card Roch Cholowsky auto — the #1 prospect chase in the set
• Vahn Lackey & Ace Reese autos — top-5 MLB Draft prospect ink
• Numbered parallels — including serialized inserts and coveted 1-of-1 variant pulls
• Base Set Variations — one guaranteed per single pack, scarcer in blaster format
• Insert sets across all box types — with short-printed chase cards spread throughout

With 23 school-specific checklists — ONIT's largest slate ever — and prospect names already making noise ahead of the draft, collectors are targeting this product now, before these names start hearing their names called in the top 10.
