Tosa 'Tengu' Washi commonly known as Tosa Tengujo-shi in Japanese is likened to the "wings of a mayfly". Made from high-quality Japanese Tosa Kozo, this tissue is the thinnest machine-made Kozo tissue available today. All Tengu tissue papers are made on a special stainless steel tissue paper machine.
The 'natural shade' Tengu Kozo is cooked with lime mortar and the Kozo bark and other impurities that remain in unbleached fibre is removed completely by hand. The colour and character of the unbleached paper is particularly appropriate for old documents of a darker tone. It is also possible to supply the tissue made with chlorine-free, bleached pulp and in a variety of dyed shades to suit even darker-toned papers or other materials where a strong but thin Kozo tissue would be appropriate to aid its preservation
