High Fire Stoneware ~ Microwave and dishwasher safe ~ Pretty significant pinholes on the outside back of travel mug. Completely Functional! Comfortably holds 14oz of liquid ~ This design originated because I wanted to create a fully-ceramic travel mug as I do not care for the taste that silicon or steel lids give. Enjoy any beverage on-the-go while knowing you are taking care of Mother Earth by reducing and re-using!
