This beautiful handmade piece has been crafted using fine bone china. Bone China is the strongest of the porcelain or china ceramics, having high mechanical strength and chip resistance, and is known for its high levels of whiteness and translucency. It’s lovely and light to hold and transcends real luxury. Please note that our mugs are dishwasher safe. Our gold-banded mugs however are not microwavable. Our no-banded mugs are.
