I know you can't mix them with other plastics but can you mix zman of different colors or will they bleed colors onto each other? Also look into the bass mafia bait coffins , zman don't seem to melt in them.
i have some zman new penny shrimp chill in with my gulp nothing negative as of yet been that way since the 21st of june, not making the date up it was important day so i remember buying those shrimp. I have used since and still same color and working fine.
