Where can I get these Japanese cups?

Question:

I can't find an image anywhere, but you see them in the anime quite alot. They look like clay cups which have been squashed slightly and are usually cream coloured. They're used for tea i think and I can't find them anywhere! If anyone can help I'd e grateful :) If this helps Histugaya Toshiro from bleach was using a similar one in episode 46 (i think or 48) When she wakes up in his office, he drinks from the cup while they talk about the paper work?

Don't know if that helped but that's all I can say -.- Thanks!
