AURA Double Wall Insulated Glass Mugs by Kaizen One - 12oz (Set of 2) NATURALLY INSULATED DESIGN - Your warm drinks will stay piping hot for longer thanks to the insulating layer of air between the two glass walls, while the outside remains cool to the touch. SET INCLUDES 2 MUGS - Who doesnt love to catch up over a good cup of coffee? Share a moment with a friend or loved one as you each enjoy using these beautiful mugs. ECO-FRIENDLY & HIGH-QUALITY MATERIALS - This pair of mugs has a sleek and modern look, handmade from premium 100% borosilicate glass so they are lightweight; plus they are completely BPA-free. MAKES A PERFECT GIFT - Tea or coffee lovers would be delighted to receive this set of two Aura mugs, especially around the holidays so they can keep warm with their favorite hot beverage. GREAT FOR ALL BEVERAGES - The insulating double wall design is ideal for warm liquids like coffee, tea, and hot cocoa, but these mugs are also great for keeping cool drinks colder! While beautiful, these mugs will require a little extra care, just like your fine wine glasses. To keep the mugs in tip top shape, avoid using hard items that could impact the inside of the mug such as automatic ice dispensers and metal spoons.
