I agree with you 100%, I cannot find a container of that size and orientation. Two days ago I found a British Tea container that is about the correct size but still has a welded seam and folded type bottom. It has the image of a red London Double Decker bus pressed into the exterior. Lots of round containers available but they are difficult to pack and do not store as well. What is needed is a BCB Mess Tin with the top being on one of the sides.

I have boxes full of potential PSK containers. I auctioned off a PSK 2 weeks ago (money went to youth group) and used a Twinnings Tea can as the container. Now I am having trouble replacing it as the local containers are all cardboard.
