When we designed our loose leaf tea set we wanted something that was completely practical, very functional and just plain simple. We felt there were so many "fancy" kettles out there to choose from. Ours were made for the person wanting simple, and quaint. Each set is made from the finest selection of Acacia wood for the wooden accents and hand made borosilicate glass for the actual kettle and glasses. This is a quaint kettle at only 600ml which is about 2.5 cups. Just enough for you and a couple friends. Just add some crumpets and you have yourself a fine fine tea time. Each of the four hand made glasses is double walled. Meaning they have a gap between the actual glass that has the tea in it and the glass you are holding in your hand. Not only does this prevent the hot tea from burning your hands through the glass but if you have a cold drink it keeps your hands from warming up the drink. We didn't invent this style of glass but we would not use any other design as they are great. The hand made acacia wood serving tray is also included. No more looking for a matching serving tray to serve your guests. Everything is included and ready to go. Just add your favorite loose leaf tea to the infuser, add hot water and serve. DELICIOUS! By the way, the infuser is removeable for simple cleaning and everything is dishwasher safe. Need to heat up your tea after its been sitting there too long? Just pop the glasses into the microwave and heat them up. The glasses are completely microwave safe. The kettle is stove top safe so if need be you can heat up your tea quickly right on the stove. Please don't put the kettle in the microwave as there are some metal fasteners that may cause damage to your microwave. Any questions? Please don't hesitate to ask. We'd be happy to answer any questions or concerns you may have.
