The Koh-i-Noor brand became the hallmark of the company, that with Faber Castell was one of the leading European pencils producers and is still on the market in the field of stationery and drawing tools. In 1919 the American branch was opened in Bloomsbury, New Jersey, and in 1931 factories in Poland and Romania were opened in cooperation with the then Johann Faber.[1]After World War II the factories in the eastern countries (Poland, Romania and Czechoslovakia) were nationalized, while the American subsidiary separated from the parent company, becoming "Koh-i-noor USA". Only the Austrian company retained its original ownership. In 1957 the Riepe Works ceded to the "Koh-i-noor USA" the rights to the nº US-3020884 of the "Rapidograph". To date, the European rights for the "L. & C. Hardtmuth" and "Koh-I-Noor" trademarks are held by "Crayomine", founded in 1960 in Vaduz.
