These high-quality plastic dividers correspond with the five Star Realms High Alert expansion packs (Heroes, Invasion, Requisition, Tech, and the Kickstarter-Exclusive First Strike pack). Use with the Star Realms Universal Storage Box. Each divider measures 6.3cm x 10.5cm.
Finally got my High Alert cards sorted instead of rattling around loose in the main box. The dividers line up with all five packs, including First Strike, and they slot in snug without wobbling. Labeling each one was a small project but worth it.
The plastic is rigid enough that these don't flop over when the box is half empty, which was my main worry. Now Heroes, Invasion, Requisition, and Tech each have their own labeled tab, so setup takes seconds instead of me digging through stacks. Only wish First Strike had a matching divider too, but
Finally got my High Alert cards sorted instead of jammed in with everything else. The dividers fit the five expansion packs perfectly, including the First Strike ones, and the labels make it obvious where each set starts. Took me ten minutes to reorganize and now setup is way faster.
