Where I used to work, orders from the machine shop or stockroom would come in tubs similar to these ones from Quantum Storage Systems. The problem was that they were always out of tubs because everyone would hoard them for storing their own stuff — there were even periodic raids to try to recover enough tubs to keep the company functioning.
These tubs nest when empty for easy storage, but they also stack alternating 90° to one another when filled. Grooves in the bottom of the tubs match with the edges to keep them locked into position.
Quantum injection-molds the tubs from high-impact polyethylene for a long life of abuse without cracking or corroding. Each tub can handle 100lbs and has holes in the bottom for drainage. The smooth surface is easy to clean and FDA-approved.
They make tubs colored gray, blue, or white. You’ll pay about $10 to $15 a tub.
