Margaritelli has created the finest wood products since 1904. The company's ongoing commitment to excellence inspired us to create Listone Giordano, patented after Professor Guglielmo Giordano, the internationally-recognized founder of Italy's National Institute of Wood Research. Margaritelli respects the environment and the forests that provide for our products. We believe in sustainability. That's why our Pan European Forest Certification from Italy's national accreditation board ensures our materials come only from those suppliers who utilize sustainable forestry practices. Margaritelli has an uncompromising commitment to excellence. We are also a proud corporate sponsor of the Guggenheim Museum.
