Our self-adhesive Pen Loop is made of a strong textile rubber band suitable for all thicknesses, from graphite pencils and fountain pens to thick wax crayons. It is self-adhesive so it can be easily attached to the back of a book, and you can carry your favourite pen on your notebook at all times. There is a matching Pen Loop for every notebook and planner colour in the LEUCHTTURM1917 range to let you express yourself as colourfully as you like. By the way, you can also creatively combine the Drehgriffel and Special Editions colours!
