It's so difficult it seems, finding storage containers that have multi-purpose uses in enough sizes without creating a monstrous mess in your container cupboard.  I am now getting rid of most of the plastic storage containers and getting organized.  I'm amazed at how much I've used these in my holiday baking already this year.  The lids are good quality and easy to put on and take off if you have hand issues.  I need a few larger ones but the cupboard is looking much better organized. :)

Pros: great value, Good Variety of Sizes, Healthier than plastic bowls, Packed well
Cons: One large rectangular or Large Bowl would've been super.
