Our pack uses Den Leader boxes. They have a wide variety of things in them. Cubscout leaders book, beltloop and sports/acedemic pins requirements, meeting dazzlers, boyscout handbook, knot tying guide, tour permits, complete set of cubscout handbooks, first-aid kit, American flag, etc. I have found the materials to be very helpful in planning my meetings. The den leader coordinator is in charge of the boxes. They are collected and inventoried every June. We get them back in August in time for the next scouting year. I would reccomend that they be used as they are a great resource for any leader.
