I use the tall narrow 250mL mason jars (same as the 1/2 pint for our american friends) but those squat ones with the larger openings look like they would be handy! I have to decant a bit of tobacco into a secondary container for packing purposes; the mouth on the tall jars is too narrow, or I am too cumbersome, to pack a bowl without getting loose bits of tobacco all over. It looks like the larger mouth may remedy that!
