This is great, much smaller than I anticipated. The large container holds about 2/3 of a 40 pound (17KG) bag of dog kibble and the small one I have full of the last bag of kibble, so I'm left with about 1/3 in the bag still. Will dump the rest of the bag into the smaller container once that is gone. Wish the large one held 40 pounds but its a great container so still gave it 5*.
