Our 15oz ceramic fired imprint mugs are the ideal size to drink your coffee or tea. Mugs come with stylized "wear and tear" to give them that vintage quality. The curved lip is perfect for taking a sip and the rounded handle allows the mug to sit comfortably in your hand. The ceramic will keep your drink from cooling too quickly, but if you're anything like us, you may need to reheat that coffee a few times before the day is done. So, we made sure you can do just that! All of our mugs are dishwasher** and microwave safe. Your drink will stay hot and your mug will stay in perfect form: no fading, no cracking. Design is printed on one side only. Our mugs are designed, fired and packaged in Edmonton, AB. **Due to Covid, some dishwashing detergent manufacturers have added citric acid to their products, which aids in killing bacteria. However, this powerful acid also breaks down the kiln-fired printing on some mugs. While our mugs are commercial grade, buyers must be aware of this possibility, particularly with some detergents, and is considered normal wear and tear and is not returnable for this reason.
