Artist-made sugar pot

I purchased several items that I fell in love with at an artist's exhibition about 20 years ago.
I've forgotten the artist's name, but they mentioned at the time that they were creating tableware for a French restaurant called Cordon Bleu, located in Ginkaku-ji.

I have carefully stored them in a display case with glass.
I would like to pass them on to someone who might fall in love with them at first sight, just as I did.
The purchase price was around 8,000 yen.
Please note that the price is firm.
Also, although they have been washed with water and are unused,
I kindly ask for your understanding regarding home storage.
8cm x 8cm, approximately 11.5cm including the handle.
