For 2 months the GL Pease tins with the polypropylene lids (used by most US blenders: C&D, McClelland . . .) are OK. I've kept them around for 2 months and not had problems with tobacco drying out, at least not very much. In the winter, you need to be more vigilant, and should consider using a piece of foil under the lid. Once the heat is on, the air in the house is really dry.
The jars you asked about from Amazon appear to be OK for keeping open tobacco for something on the order of a couple of months, maybe longer. Probably better than the GL Pease tin? But I'd not risk it for long-term storage.
However, for the price of one "tobacco" jar, you can buy a case (12 jars) of half-pint mason jars from the hardware store (or K-mart or Target or . . .). Mason jars are good for short-term storage, and are the absolute best for medium and long-term storage.
I don't quite understand why some are reluctant to take the plunge and get some mason jars. I was the same way at one point -- go figure. Mason jars are really the only way to go. You don't have to be one of those guys with 500 lb of tobacco aging in the cellar to start using some mason jars.
