In my shop there is a ball shaped sugar bowl with black dot pattern and red bird, which matches the pot perfectly! If you buy the sugar bowl together with the teapot you only have to pay shipping costs once.
The teapot is an antique one, I think from about 1960, but it still is in perfect condition. The brand is 'Bavaria', high quality porcelain. It is fired on high temperature and suitable for daily use. I recommend it to just wash it by hand although it should be dishwasher safe.
