Pen/Pencil To maintain the lustre of your ballpoint pen/propelling pencil, avoid exposure to household bleach and other cleaning products, which can quickly cause discolouration. To clean, gently wipe the surface of your ballpoint pen/propelling pencil with a polishing cloth. Avoid commercial liquid polish or `dips’. When not being used, we recommend that you store your ballpoint pen/propelling pencil in your soft lined individual pouch to prevent them being scratched.
