Made of bone china. It is stronger than ordinary porcelain because it contains bone ash. This additive makes the walls thinner and stronger.
How to use
Pour warm water through the spout. Place solid shaving soap on top. A Truefitt & Hill brand hemisphere-shaped soap, such as Sandalwood or Luxury, is ideal. Whisk the moisturized shaving brush and shave. Excess water will drain through the holes inside the mug and the soap will dry.
The exact same mug is available in black.
