Not certain of exact age. Most of what I sell is from my home and I have owned these since 1970. I can only list 12 pictures so I tried to show flaws.
Rice container has repair to rim and the white bands are eroded. Sugar has crack in cover. Bean jar has small chip in rim. Various glaze issues exist such as drips and roughness.Tea is a good example of the worst. Colors of covers also vary from bright to dull tan. All of which makes me think these are hand made. Look at photos carefully and ask me for more if you are interested.
