This is a great storage container. I use it to store my kitty's bag of Hill's Science Diet. It keeps food and treats from getting stale, with or without keeping it in a bag. I bought it in a size large. It came with a big scoop which can be stored in the lid. There is a lip that it easily slides onto.
I don't use the scoop that came with mine. It holds 1 1/2 cups, and I feed my cat 1/3 cup at a time. The scoop didn't have any markings and I found it hard to gauge how much I gave her. I gave the scoop away to a family member who uses it in her garden now as a mini-shovel. Reuse, recycle.
The dimensions of the bin are 20.74 inches (width) x 23.37 inches (height) x 11.77 inches (top of bin's length). It can hold up to 58 pounds of loose dog food, 63 pounds of loose cat food and 86 pounds of loose bird seed. The base of the receptacle is made from high-density polyethylene. It does feel really sturdy and strong. I feel confident that this keeps food especially fresh because it has an airtight dual-foam seal. It also has a click-together closure at the top that has consistently worked over months of use.
