How would you love to keep your coffee warmer longer? I know this is always an issue for me until I started using this cork base coffee mug. The cork keeps the heat in the coffee mug longer and protects your surfaces at the same time. To top it off, who doesn't just love a little "Highland" cow looking back at them as they drink their coffee? Enhance your daily ritual with this charming and functional Highland Cow Ceramic Coffee Mug from Crafts By Effie, where custom gifts like drinkware meet thoughtful design and practicality. 14 ounces with cork base and spillproof lid. Custom orders also accepted see below for options.
