The papers all come from the Pelletier paper mill in Brussels; the purveyor to the Belgian royal family was one of the first manufacturers to provide envelopes with a lining of tissue paper. In addition to the stationery (100 gsm) - available in A4 as a letter pad or single sheet with "Original Crown Mill" watermark or in A5 as a letter pad without watermark - we offer matching letter cards (280 or 300 gsm) each with a firmer structure as well as lined envelopes in two formats.
