Each of the two bins in this set holds 4.5 gallons, roughly 35 pounds of rice or 17 pounds of dry pet food, so a large sack transfers straight out of paper packaging into a sealed store. Sealing runs through clamping buckles, two silicone rings and a desiccant box, a combination that keeps moisture, pantry insects and odour out of grain, cereal, flour and kibble for far longer than a folded bag clip. Food-grade Pp construction is Bpa free and wipes clean between refills. Detachable 360 degree wheels roll a full bin out from under a counter without dragging, which matters once a container is loaded to capacity. The lid is flat so bins stack vertically and a second layer of seasoning bottles or small tins can rest on top. A transparent cover with scale markings shows the remaining level at a glance. Two measuring cups are included. Overall size is 14 by 9 by 17.5 inches.
