Bring on that busy day. Enjoy your hot or cold drink when you are on the go in the insulated mug Ellipse 375 ml. The insulated mug keeps your drink hot for up to 4 hours and cold for up to 8 and is naturally 100% leak proof. Great: as soon as you screw open the lid there will be instant coffee chemistry (or tea chemistry with your favourite tea). The mug fits in practically all cup holders which makes it easy to take along.
