Mason jars really are the best. Some people say plastic bags or jars give a flavor and degrade the aroma. I've used plastic jars and haven't noticed anything bad but plastic baggies are not very efficient in my opinion. Buds always end up to dry by the end of the bag. I keep them in different sized jars depending on how much I have. At walmart you can get cases of jars. Might be more than you need but they aren't very expensive. Like $8 for a set of 12. The smallest ones are great for a quarter of dense nugs. While the medium sized ones can hold a half ounce of fluffy nugs. If you have serious weight then get the quart sized jars. I try to keep the jar at about 80% full.
