Thank you for viewing. This was a gift for a new life, but I have only used it about three times. The white one has a smooth texture, and the black one has a rough texture. Please use it for tea or for enjoying drinks in the evening. The capacity is about 300ml, so it's a generous size. It came in a wooden box, but I have discarded it, so I don't know which brand it is. Please understand that this has been stored by a private individual, and consider purchasing. I will wrap it in packing material and ship it in a cardboard box.
