2018 Bowman High Tek Baseball Base Set
It’s all up-and-coming prospects and rookies when it comes to the main 2018 Bowman High Tek Baseball set.

Every base card has ten different background variations. The first pattern is the most common in each box and is considered to be the base. Ensuing pattern numbers are increasingly difficult to pull until you get to Patterns 9 and 10, which are both one-of-ones. Pattern 9 cards are called SpecTEKular Diffractors while Pattern 10 are Black Galactic Diffractors.

Parallels combine to land one per box.
