I keep them in Plano trays with bait slots to keep them separated, and keep them straight. So far every brand I've taken on tends to let them warp and lock in to whatever position they remain in a long time. None have dried out so far. I wouldn't spray them down as that would let them slide around like wet snot in there
I like them laid flat and parallel, none able to fall out of position. Also, I've had some bleeding colors from putting used swim baits back in the tray with attractant on them. It might have been anise oil, or something else.
I clip the name tag off the bag and lay that under each model in case I want to know exactly what is or was in a slot.
