Tubs from Quantum Storage are manufactured using USDA and FDA approved polypropylene. They can be stored tote nest when empty and can also be cross stacked at 90° angles when filled with items. When the tubs are stacked, they provide easy access to the contents stored inside and the high impact polypropylene is easy to keep clean. Handles are integrated into the design, making handling very easy. Grooves have also been molded into the bottom of the bins, allowing them to be stacked securely. The bins hold up to 100lb and have a six 1/14" drill hole pattern in the bottom for when drainage or air circulation is required. They are available in gray, blue and white.
