They look a lot like reading tubes and would be the right size if the juglike containers are the small phials, but since they are drawn at the same scale as the two rows of jugs, and the jugs might be intended to be something bigger than phials, I wonder if they are albarellos, like the ones that are mostly straight-sided. Or possibly the wooden kind. Here are some examples of straighter styles of containers:

Decorative patterns of horizontal lines were common on these jugs but the drawing isn't good enough to tell if the lines are decorations or functional (like lids or tube portions).
