Looking for Yixing cups

Greetings,

For some time I have been looking for some particular Yixing cups to my puerh teas, but so far I could not find an online vendor that has them in the wanted size and design. (Actually I have found one, but he would only sell me a complete gongfu set with tea pot and tray.)

The cups should be dark brown Yixing clay, glazed white inside, like these ones:

I am quite picky about the size, too: the diameter should be 5 cm (2 inches), and the height 3,5 cm (1.4 inch).

I would be thankful for any suggestion for an online vendor who would ship to Europe.

Thanks, Gyorgy
