Whether these are a demitasse set or tea cups, they are a beautiful green and gold set.  The original tags say "made exclusively for Italian Design Service.  They are in their original red and gold circular box with the cups laid in a silk like material and the saucers still in their original plastic wrap,  each marked with GNA in its symbol and fine porcelain below.

When we searched the internet for the price we found similar sets from $39.00 up to $200.  unfortunately we found a chip in one of the cup bases so we are offering this beautiful set at a fraction of its worth.
