One of the primary benefits of double wall glass mugs is their excellent thermal insulation properties. With a 500ml capacity, these mugs can hold a substantial amount of your favorite beverage, and thanks to the insulating air pocket, your hot drinks stay warm for longer periods. Conversely, they also keep cold beverages, like iced tea or cocktails, chilled. This feature is particularly advantageous for those who enjoy sipping their drinks at a leisurely pace; the double wall design ensures that you won’t be left with a lukewarm cup of coffee or a watered-down iced drink.
