• Set of 2 double-wall mugs measuring 3-1/2 by 5 by 4 inches and holding 10 ounces each
• Mouth-blown, lab-quality borosilicate-glass construction; durable and heat resistant
• 2-layer design creates dramatic optical illusion and prevents condensation
• Safe for dishwasher and microwave use; not for use with metal utensils
• Freezer and ovenware safe

When form follows function, design just works. Abiding by this belief, the Bistro Double Wall Glass Line serves best if used to keep ice cold drinks cold and hot drinks hot.
