Good product - easy to stack, good size for refrigerator storage
My wife like to cook in bulk, then freeze part of it for later use.  These are pretty much perfect for that.  Good deal on a price per unit, too.  Added to which they are freezer and microwave safe.  They seem sturdy, too.  Recommended.<br /><br />Update - the blue covers are brittle and very easy to break, particularly if they are cold (coming out of the freezer).  Still a pretty good deal, considering the price, but no longer recommended.
