The Kona Bistro Mugs are ideal for both hot and cold beverages. The C handle is designed to allow consumers to hold the mugs easily. They are made of two-color glossy stoneware with white color inside and a different color on the outside. This dual color feature makes them very trendy and an ideal alternative to traditional white stoneware mugs. Our mugs are microwave safe with non-metallic ink used. They can be used as great promotional items for your business or giveaways for any event.
