   The Rumanian company Flaro (short for Flamura Rosie, i.e. Red Flag), established in 1948, has been making stationery, office supplies and haberdashery since the 1950's. Flaro was the first Rumanian company to make ‘plastic products’ and is most famous for its fountain pens. It is based in Sibiu (Hermannstadt).
