Sum porcelain cup

‘SUM’ is a collection of porcelain in which every choice for detail, color and finish during the production process has a direct influence on the final result and price. 
'SUM' sets of 4, mugs or espresso cups, are available in two different finishings and come in a range of blue or grey colors.
The "smooth finish" is a finish with glazing on the inside and a non-glazed and soft sanded outside.
The "raw finish" is a basic finish with a random flow of glazing on the outside of the cups.
