It's a plump and well-balanced shape. It is not heat-resistant glass, so it cannot be used over an open flame, but it is okay for uses where the temperature will gradually decrease, such as slowly dripping coffee. However, it is weak to sudden temperature changes, so on cold days, it's best to warm it up by briefly rinsing it with lukewarm water. It can also be used for cold brewing tea leaves or herbs, or as a decanter. Unused, stored. I'm not sure if it's from being stored on a shelf or from the store, but there are some scuff marks. (Around the bottom right of the 7th image). I hope someone who understands this will purchase it. ....... Tokiko Kurokawa Studio Prepa Kazumi Tsuji Miyukiko Tsuji SCOP Iittala Kaj Franck Nordic
