I use these for my Gulp baits.

They work great, keep them from spilling like the regular Gulp jars. I can fit 3 or 4 jars of 1in Gulp minnows in a jar (4 may be a little too full). Keep one of minnows, 1 of the imposter spikes and whatever else. Other two are for chopped shrimp, and perch eyes in oil.
