This plunger is crafted from heat resistant double walled glass and solid oak with a stainless-steel insert. The double walled glass keeps the beverage hot for longer as the outer glass wall remains at room temperature.
Each oak top and lid is individually carved by hand and finished with a blend of natural waxes and food grade mineral oils, that makes them smooth to the touch. These oils and waxes exceed FDA regulations for direct and indirect contact with food. The glass is microwave-safe and dishwasher-safe. (The lid and the insert should always be washed by hand. Never place timber in the dishwasher. Simply rinse and place on edge to dry.)
