Features: - Precise - AIR is not a water heater and cannot be used with direct heat sources. It can only be used as a water dispenser that is heated in a suitable kettle. The profiled spout allows you to control the water flow, which is useful when pouring coffee. - With scales - Transparent walls and markings up to 350 ml in 50 ml increments enable coffee preparation without the need for a scale. Simply add as much water as you wish to brew. This is a great solution for people who consider proportions a normal factor and do not want to purchase additional equipment. - Durable - the jug is made of food-grade PCT resin. The plastic is more resilient than glass and easy to transport. The cup is made in Japan.
