These are just what we needed for our prepping needs, the screw on top with a rubber seal is just so practical and handy. The rings were a little difficult to get on so I took a 1'' x 4" x 24" piece of wood and used my (body weight) knee and palm of my hand to press down center to center... then turn it from side to side and did the same working my way around, if you end up with to much bucket rim on one side just take the ring off and start over. These are so worth the price to securely store food and items in case of storms or other natural disasters. One bucket will hold 50lbs of white sugar with no room to spare.
