I have some of the wide mouthed jars also. I love the way they look, but they don't stack as well. Some time back, I started using a paper plate for loading my pipes. I keep one on my shelf and just dump out a little tobacco and load my pipe from the pile over the plate. That way I spill loose tobacco on the plate, not my table. Then I just taco the plate and dump the leftover tobacco back in the jar. This eliminated my need for wide mouthed jars, because I don't load my pipes over the jars anymore.
Peace,
Bill
