I've just purchased a few of the Fido clamp lid and rubber gasket jars from Crate and Barrel. They come in 1/2 liter, 1 liter, 2 liter, 3 liter, and even a 5 liter size, plus extra rubber gaskets. On sale right now, and ship for about $5 flat rate. And man oh man do those Crate and Barrel people know how to pack them well for shipping! Mine arrived about 3 days after ordering. Love these things! Much easier to use for tobac you want to get into more frequently, in my limited experience. They are pricier than Ball jars, but they work better for me with the clamp rather than the screw top. But Mason or Ball are definitely less expensive if you need a lot of them. My stash is still small, so I only needed a couple in a few different sizes.
