Thank you for viewing. This is a medicine dispenser for patients. It's made of glass, so it's clean. It is not heat-resistant. Please use it with warm water. The glass part is made in China, but the other parts, the mouthpiece and brush, are made in Japan. The brush is for cleaning the tip of the mouth. It's an unused item, close to new, but it has some dirt and dust due to long-term storage. I named it "Pine Mark" hoping for a quick recovery from illness and patience. The box is a little dirty. Dimensions: Height 8cm, Length 10cm, Circumference 10cm. Please note that these are amateur measurements. To keep the price down, I will ship it via regular mail, carefully to prevent breakage. If you prefer Mercari delivery, please add 100 yen. Please comment. As an alternative use, how about using it as a flower vase?
