This is a traditional Okinawan Kyokun Chawan (Lesson Teacup) made at the Yoneko Pottery workshop on Ishigaki Island. It's called the "Hara Hachi Bun Me Chawan" (80% Full Teacup), and if you pour more than a certain amount of liquid, it will all spill out. It's a peculiar teacup that can only be used if you pour a fixed amount, mindful of the 80% full rule. Therefore, there is a hole in a specific part, but this is part of the design. See the image. It's brand new. Palm-sized. Thank you. This is a very rare and cute item that you don't often see. It's also a lucky Shisa, so how about it?
