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 replacement blade for the MAPED Mapet 45° cutter, which is used in conjunction with the slide ruler imported from L'ECLAT DE VERRE in France. Since only the diagonal corners can be used, it is recommended to change the blade frequently to maintain sharpness. There are 10 blades included. *The last image shows the price from L'ECLAT DE VERRE in France. It is 8.50€. *Although it is new and unused, the plastic cover has discolored due to sun exposure. #FrenchFraming #encadrement #framing #MAPED #SlideCutter #ReplacementBlade #45°
