Safe and easy to use, the Aerolatte milk frother eliminates the need for expensive steam-based machines. It works directly in your mug or glass using an innovative whisk-head to turn milk that has been heated in the microwave or stovetop into rich, thick foam in just 20-second. Use for lattes, cappuccinos, milkshakes, and hot chocolate. Aerolatte Union Jack is decorated with the British flag and comes with a travel case. Includes directions, recipes and two AA batteries.
