This is a glass cup featuring the cover design of "I Am a Cat." It's a souvenir from the "Natsume Soseki's Art World Exhibition" at the University of the Arts museum about 15 years ago, which I purchased at the time. I've kept it on display and haven't used it as tableware. Diameter is approximately 8 cm, height is 8 cm. No pets, no smokers. I've stored it carefully, but please understand that it's been kept by an individual and there may be some age-related wear and tear. It will be sent via anonymous shipping. I will respond after 8 PM. It will take about two days to ship. Instant purchase is welcome, and no greetings are necessary. Feel free to ask any questions you have about the product.
