Retors Book Binding Linen No. 12

Made by Maison Sajou, France. 50g

The size of our binding book threads is expressed in metric number (NM), which corresponds to the number of metres per gram or the number of kilometres per kilogram. It is said that to express the thickness of a thread by a metric number is a false friend: the indicated number is proportionally the opposite of the thickness of the thread. Thus, a No. 12 is thicker than a No. 30.

It is waxed, having passed through a starch and beeswax bath, making it resistant and solid.
