I was at Office Depot the other day and saw tons of these things in all sizes. I was very impressed with the sturdiness and tightness of the lids. There are absolutely no ridges on the insides. They stack flawlessly on top of each other. The price tag is higher than Sterilites or Rubbermaids but it sounds like it may be worth it.

I'm looking to make a new tub for my BP. Any experience with these, or possible issues as enclosures?

a couple examples of the larger ones they have -

70 liter (inside dimensions 27x21x7)


64 liter open-front (inside dimensions 24x14x11)


Thanks!
