6 antique white wine glasses in blown glass late nineteenth century

Set of 6 antique white wine glasses in blown glass late 19th century. Roll shape with flat ribs. Height 11.5 cm. These old pieces are in good condition, no shine. Ancient manufacturing at the beginning of industrialization, there are traces of a time when manufacturing techniques did not allow the precision of today: bubbles caught in the material, undulations, deformations, irregularities. All the charm of mouth-blown glass! Neat and well protected shipment.
