last week i ran to michaels to see if they had any mason jars and i found one that will hold aobut an ounce, is airtight and was only 99 cents lol. id say go to just about any arts and crafts store and they will have them and their so much cheaper than i had expected. I also have a little jar that will hold about 5 grams and it is from an older fish bait container but cleanedd it out and its works awsome.
