As the name suggests, these Lebaufil threads are made of metal. Not to be confused with the Fil Au Chinois metallized threads which are metallo-plastic.The gold, silver and copper are available in three diametres, the other colours in two. These threads are used for jewellery work and can also be used in crochet. Both the elastic and metal wire threads are a speciality of the Lebaufil brand, who have been making them in France since 1946. This company was taken over in December 2015 by Ets Toulemonde, already the owners of Fil Au Chinois, Laine Saint-Pierre and the Decouvit brand.
