I have been using and liking these, but I will be letting them go as I have started using Scandinavian tableware. They are similar but slightly different types. One has what appears to be limescale stains on the bottom. Each one is handmade, so they have slightly different expressions. The air bubbles look like polka dots and are cute. They are also a good size, so you can drink a lot from them. I think they cost around 800 yen each. I will sell them at a low price. Would anyone who likes them be interested?
