LEUCHTTURM1917 Pen Loop XL features a larger elasticated loop attached to a strong adhesive pad. The pad sticks to the inside rear cover of any notebook to add a useful loop for pens or pencils. Accommodates pens/pencils up to approximately 20mm in diameter, perfect for those fountain pens and markers that don't usually fit in pen loops! Ideal for any of our great range of LEUCHTTURM1917 notebooks.
