Good strong lugs (I recommend the Akro-Mils 34005 lid to go with it; the lids do NOT snap onto the lugs).The lugs with lids can be directly stacked, or criss-cross stacked.These are big, strong, and smooth. No hard to clean corners or ridges.Each bin can hold 55# of ground 'sausage'. Any bigger and it's too tough to handle them.I bought 6 VERY similar looking lugs and lids e-Bay 5-7 years back,and as similar as they look, they are NOT the same! The lids for these lugs don't fit the old lugs,and vice versa. That's a bummer. When I bought these, I just assumed they were the same bins.BUT that's no ones fault but mine, so no lost star. They are so similar I need a system to tell the setsapart, otherwise I have a 50-50 chance I'll grab the wrong lid.
