Produced manually by glassblowers from heat resistant borosilicate glass (made in Ger-many). The tea pots include a separate tea warmer and a special glass body with a warm-ing tube and a top. In order to ensure air and heat traffic, this top also has a slot in the middle. The stainless steel tea warmer enhances the enthralling atmosphere created by the light in the tube. This internal tube allows the tea to glow, thus creating unique opti-cal highlights in your home. Working their magic together, the special glass body and the tea warmer will keep your tea hot, while adding a romantic touch and allowing you to enjoy a new tea experience.
