binkop glassBINKOP is a glass cup made in Japan using the same manufacturing process as glass bottles. Like regular glass bottles, it is made mainly from crushed used glass bottles. It is thick walled and durable, so anyone can use it easily. It is also recommended as a first glass cup for small children. Also, although it is not heat resistant glass, it works well with hot drinks. If you have to throw it away for some reason, please put it out as a glass bottle;
