when u buy a box of worms from the bait shop how big the the box ( I mean what does the box measure I'm going to make a tray to set a box of worms in that attaches to my home made rod holders but just don't have a box of worms to get measurements from ) so I'm needing the square measurement and the round measurement would be nice also and after I get them made and mounted I'll get some pictures up so y'all can see what I'm working on
