2018 Topps High Tek Baseball

With two on-card autographs per box and a multitude of patterns done on acetate, 2018 Topps High Tek Baseball is still one of the more unique MLB sets every year. Although it maintains the same basic output as 2017 , High Tek 2018 makes a few changes. The base set again contains current stars, top rookies and retired greats, adding many different versions to track down. Options include Rainbow Foil (10 per pack), Magma Diffractor (3 per pack), Orbit Diffractor (2 per pack) and Galactic Diffractor (1 per pack).
