Enhance your coffee and tea drinking experience with the Avanti Huggie Double Wall Mugs.Stylish and practical, they create an optical illusion with a floating effect and are also suitable for soups and desserts. Crafted from heat-resistant borosilicate glass, each mug is individually mouth-blown and is designed with a double wall for thermal efficiency to keep contents hot or cold for longer. They feature a safety vent at the bottom that equalises the air pressure between the two layers of glass when either hot or cold liquids are added. With generous handles, the glasses are cool to the touch and will protect your hands from the heat of piping hot drinks while offering freedom from annoying, dripping condensation around your favourite cold beverage.Features:450ml CapacitySuitable for hot and cold beveragesCrafted from heat-resistant borosilicate glassDouble wall construction for thermal efficiencyMaintains the temperature of hot or cold drinks for longerSafety vent equalises air pressure between the two layers of glassPrevents condensation on the outer surface with cold drinksLightweight and durableFine smooth rim for comfortable sippingGenerously sized handlesMicrowave and oven safe to 175CFridge & Freezer safe to -30CDishwasher safe
