In the office, we often lend pens but it is rare that they come back.
And sometimes, they are borrowed from you without asking permission...
Are you tired of having your pen stolen at the office?
Try this trick against office pen thieves:
Put a blue cartridge in your red pen.
Why ? Because no one steals a red pen.
And that's it, no one will steal your pen anymore :-)
Practical and efficient!
