Do you have the internal dimensions for those? They aren't clear from the information on the site. The wife and I do a lot of what we call 'bottling' which means mainly fruit from our trees preserved in Kilner and similar jars. The main problem we come up against is getting efficient use of the space inside pressure cookers. We have several, but there always seems to be a huge unused void in the container. Most of the time if the thing was an extra inch tall we could get twice as many jars in there. It's very frustrating. The retailers seem to be able to tell you the internal diameter easily enough, but much less often can they tell you the maximum usable internal height. Seems a bit selfish.
