Where do we start Our large Smart Storage is stackable and airtight with rubber gaskets on both the large and small openings that keep both weather and pests out. It can hold up to 50 lbs. of food (depending on size of kibble), has the largest top opening in the 50 lb. category, and you can access the contents of the bottom bin with another unit stacked on top. With a great on-trend color, it’s a must have!
