I use a glass mason canning jar, like most of the responders. For my larger stash, which is in a bag, with a Beveda pack,I have kept it in a 1-2 gallon bucket from the grocery store bakery, it seals and you CANNOT smell at all! They usually hold frosting. The seal is unbelievable and they are FREE! It is like the snap on lids/bucket from the big lumber store, except it has a rubber ring in the lid.
