Babby food jars stuffed tightly with cotton. you can get 4-5 in a jar but use a pen or arrow to stuff the cotton balls in so you don't get cut.

I have a plastic tool box with all my bow stuff in it. I cut a piece of dense foam and push the BH's in and keep it in the bottom of the tool box. I cut the piece of foam so it just fitswithno jiggling. All my heads are secure and stay sharp while awaiting deployment.
