There’s circumference of these erasers is too small for my vintage Parker jotter pencil. However, I wrapped some scotch tape around the base of the eraser, and now it fits OK. The eraser itself is very good.
I am a yacht designer and the Isograph are my tools.
I am very glad to do business with Pen & Pencil. My order was shipped very swiftly and the nib was perfect. I will certainly come back.
Many tanks.
