Showa Retro Ceramic Tea Set, 5-Piece Set, Unused, Long-Term Storage Item

I am listing items that are no longer needed as I am organizing my grandparents' house.

These items are unused but have been stored in a warehouse for a long time.

I will send the items shown in the photos.
Please judge the details of the teacups from the photos.

Before shipping, I plan to wash them with dish soap and remove them from the box for packaging.

Immediate purchase is welcome.
Thank you for your consideration.
