Thank you for viewing. I learned French framing in Paris, France, and have been teaching it in Japan for 20 years. I am selling items that are no longer used in my atelier. This is a thin ruler purchased from a bookbinding atelier. I'm not sure how it's used in bookbinding, but it was very convenient for cutting paper and thin paper on top of this ruler. Both corners of the edges are bent. There are faint marks where the atelier stickers were placed. Recommended for those who don't mind scratches. 5 x 28cm 19.5 x 28cm The thickness is so thin that it can't be measured. #FrenchFraming #encadrement #Relieur #ThinRuler #2Pieces #WithScratches #StainlessSteel #Bookbinding
