• 100% hand-made and engraved cup, it is executed over a long period and goes through many stages to produce a piece that suits you. It is impossible for two cups to be exactly the same in shape, as the color coverage, distribution, and density may differ.

• It is recommended to use warm water, not boiling water, for the first few times of use.
