My experience with buying method is fine. I have bought: article number 502251, van Gogh Espresso set, Almond Blossom, dimension 11 cm x 11 cm x 6 cm, weight 156 g.
Improvements or suggestions
My interest is to purchase greater porcelain coffee set, Almond Blossom with dimensions16 cm x 16 cm x 7 cm and weight 390 g. Such a set I have bought in your museum a few years ago and have now an interest to purchase by internet.
