Celebrate your clan heritage with this heirloom quality 8 z. mug with your clan crest on the front and clan tartan on the top rim and down the handle. Made in Scotland of bone china, this mug is lightweight and durable. Please note the gold edge will spark if used on the microwave. We also suggest placing a metal spoon in the mug before pouring in boiling hot water! The spoon will buffer the heat and protect the mug from heat shock which can crack the mug over time.
