Antique Tin Round Sencha Cup Saucer Set of 5 16th-19th century

It is a round-type old tin teacup that is slightly small and has a raised rim that looks good on a teacup. We have 5 customers. How about as a daily tea utensil? A wooden box is included, but the condition of the lid and bottom of the wooden box is not good.

We have posted many product photos, so please check the details and condition.
