Heavy-duty EZ Stor™ containers/buckets are rectangular in shape and are made with virgin, high density polyethylene material so they are super tough and super easy to store! These patented containers have no holes in them and can hold up to 8 or 13 gallons of liquid. They work well for mixing solutions or for building your own mega hydroponic system. EZ Stor™ containers are nestable, with built in hand grips, making them easily transported. The lid is compatible with both sizes. It has a recessed fit with a tear strip and a built in handle on the front portion of the hinged lid, creating easy access without removing the lid.
