A perfect companion to your expertly brewed tea or coffee. Bodum Bistro Double Wall Mug Set in 2 Piece is ideal for keeping your cold drinks cold, and your hot drinks hot thanks to the special double walled glass thermal effect. These Mugs are made from high quality heat resistant borosilicate glass with a beautifully curved glass handle. The glass brings out the beauty of the brew which heightens the senses and allows you to anticipate the next sip. The improved design includes a hydrophobic silicone vent at the base of the glass which allows the air pressure to be equalised automatically whether there is hot, cold or no liquid in the glass. As they are made from borosilicate glass, they are strong, sturdy and can withstand dishwashing without clouding the glass. All of this adds to the practical and functional nature of these Bistro Espresso Mugs. These versatile Double Walled Glasses are dishwasher, microwave and freezer safe.
