Soup bowls, set of 4 with lids

This is a set of 4 lidded soup bowls.
They are not sold individually.

These were found during a decluttering of my belongings. I believe they were a gift received about 30 years ago. They have been stored in a dark place without ever being used, and I have no plans to use them in the future, so I would like to pass them on to someone who needs them.

Regarding the condition of the items, both the bowls and lids are free of dirt, cracks, or chips. The painted designs are also free of peeling or scratches and are in beautiful condition.
I believe sets of 5 are usually standard for this type of item, but for some reason, this set only has 4 bowls. There are no instructions, so I cannot determine if it was originally a set of 4 or if one bowl is missing from a set of 5. Therefore, I have listed the condition as Near unused. (Although I have no memory of using them.)
There were no instructions or anything similar inside the box.
Regarding the size, the diameter of the soup bowl is 118mm and the height is 75mm. The diameter of the lid is 111mm and the height is 35mm. The storage box measures 208mm in length, 132mm in width, and 129mm in height. (Please note that these are amateur measurements, so please allow for some error.)

Please check the photos for details.

As there are no instructions, I do not know the material of the bowls or lids, nor the details of the painted designs. Please understand in advance that I will not be able to answer such questions.

Furthermore, as these are long-term stored items from personal ownership, please refrain from purchasing if you are overly concerned about the condition.

Due to the size of the item, it will be shipped via Yuyu Mercari便 (Yuu-Pack). The price includes shipping, so please refrain from negotiating the price.

Although they have been stored for a long time, I believe they can still be used. How about them for someone looking for lidded soup bowls?

Thank you.
