Yes, these milk crates are the real McCoy. The hard to find, commercial-duty milk crate so sought after there's practically a black market for them. We even know people – dependable upstanding members of the community – who have been known to steal them and hoard them, they're so useful. But now you can have all 1001 uses for these stackable crates without resorting to a life of crime. Made by the American-based commercial supplier of these crates (not some cheapo version like you find in discount stores). Constructed of what might look like run-of-the-mill plastic but is actually HDPE (high-density polyethylene resin), capable of carrying 4 gallons of milk, or 35 lbs. or more. Great for carrying tools, cords, supplies, for trunk storage, closet, shop or shed storage and stacking to maximize storage in small spaces.
