Thank you for viewing. I am selling heat-resistant glass tableware from Iwaki Houseware Co., Ltd. ★ The round shape allows tea leaves to "jump" easily, allowing you to enjoy a rich aroma. ★ The tea strainer can be removed and washed, making it very hygienic. ★ Microwave safe, not for direct fire. Actual capacity: 640ml It comes with a box, but it has faded due to long-term storage. Although it is unused, I would appreciate it if you could purchase it if you understand that it has been stored at home.
