Grá Mór Claddagh Mug

 These mugs are safe to use in dishwashers & microwaves.

However, there is a small possibility with any product like this, that prolonged usage over time in a dishwasher or microwave may start to effect the design.

Very high temperatures, hard water & harsh detergents may cause the design to fade/peel over time.

 This ceramic mug holds up to 11oz's (325ml) of hot or cold beverages.
