The Mountains are Calling coffee mug is made from my original paintings, perfect gift for the camper, hiker or nature lover in your life! The image is on both sides of the mug. This mug holds 13oz of liquid, and is a nice sturdy ceramic camp mug. These mugs are made by hand in my studio using the sublimation process so the image is permanent on the mug and are dishwasher and microwave safe! Option to choose a white mug with the black rim, or a cream speckled mug with the black rim- as shown in photos. Please note for mug orders larger than 20 pieces, I may have to order more mug blanks which will extend production time.
