The WD40 Magic Pen is a great invention. It's a handy little brother of the classic WD40 can. The magic pen has all the benefits of WD40 but in a special space-saving pen design. This makes it an extremely useful item to carry in any motorhome or campervan drawer. It is an easy to operate squeeze action pen, which can be used on hinges, locks, basically anything squeaky. The pen design ensures application is direct with no excess to wipe away. Now that is magic!
