I was wanting to write a review about them but can't find a way to do it. These are AWESOME containers. I had one outdoors down in a stump hole and it rained for 2 days, I went to get the container and it was completely submerged in water, It was underwater for 2 days and when I opened it it was dry as could be inside. Absolutely no leakage or dampness inside. I have told all my friends and family about them. They are AWESOME!!!!!Thanks!" -Randy
