Grab you a case (12) of half pint kerr canning jars for about $10 or so at your local grocery store. Take em home clean them up real good, drop your samples in them and just be sure to screw the lids down tight after dipping into them each time for a smoke! Should last pretty much indefinitely for the most part. (well maybe only a few years of opening & closing the jars multiple times a day!) Be sure to label them!
I've learned the canning jars are wonderful storage devices. The canning jars will keep your samples pretty much exactly like they were the day you put them in until they are gone. No need for a vacuum sealer at this stage! Open, Close, Enjoy!
