Lime Green Keychain Pen features a working pen in vivid green with a gleaming rhinestone band around the middle. Simply twist the barrel to make the black ink ballpoint nib extend for smooth, fluid writing. A sturdy lobster claw clasp keeps it attached to key rings and purse straps, but lets you detach it quickly for when you need to write a note in a hurry – never have to dig in your purse for a pen again! Keychain Pen measures approximately 2in tall.
