Savor your coffee or tea in all its flavor and splendor when sipping from the Double Wall Stripe mug. Two layers of lightweight borosilicate glass are mouth blown together to create a unique glass-in-glass effect. The result is a vacuum layer of thermal insulation that either keeps drinks hot and easy to handle or preserves the cold in your drinks without wet condensation. The beautiful details of the stripes on the outer layer gives the mug an added dimension of chic beauty. Also, a great gift idea for your loved ones or even for yourself.
