Most origami will not last for hundreds of years in the open air. Paper crumbles, fades, and creases broaden. Origami from the late Japanese master Yoshizawa was folded using a special long-lasting paper that was manufactured by only one company, wrapped in gauze and placed in a succession of wooden boxes and placed on a shelf in a humidity controlled room. The jar is nice, but I wouldn't want dozens of them in my origami studio. Plastic boxes serve the same purpose, although the bell jar may provide better air tight protection. Obviously, someone is trying to sell bell jars, why else would the tags still be on the top of all the jars in the photos? And yes, the origami would fall over if the jar is moved, unless it is tacked down.

I agree. The oragami is wonderful but I think describing putting a jar over it as "amazing" is an overstatement.
