Our mouth-blown, double-wall tumblers are the perfect combination of style and functionality. The unique flared rim delivers wine to the tip of your tongue, ideal for appreciating delicate wines such as rosè. The double wall design creates a dramatic optical illusion of your beverage 'floating', while simultaneously helping to maintain desired drink temperature; protects cool drinks from the warmth of your hand and protects your hand from hot cocktails or coffee. Ideal for everyday use. Lead free glass. Dishwasher safe.
