This ceramic Joy Christmas Wreath Watercolor Coffee Mug is the perfect gift to share Christmas Cheer! It holds 11 fluid ounces or 325 milliliters. The heart image is on both sides of the mug so this gift is perfect for a lefty or righty! The watercolor heart image was handpainted by me and edited in photoshop to ensure there are no edges or squares on the mug. The Mugs are fade resistant and yes they are microwave and dishwasher safe too.
