I have about 4 dozen that have been collected and purchased thru Craig' list over years. Like the 6gl size for 330's they hold 10 asstd brands nice and neat and make keeping track how many I have out by just counting them x10 at the end of the day. Pretty much the same with other kinds/sizes of traps by keeping same number in each crate of them. Makes it challenging some summers replacing the odd stolen/broken traps each season. I don't pile as many in each crate now as I used to any more. They must be heavier now , or I'm getting older, lol.

A 25 lb propane bottle fits nicely in a milk crate and is more stable, especially in a truck bed.
