Post-it Message Flags feature "Sign Here" messaging. The Yellow 1" wide Post-it Flags help you draw attention to and request specific actions to help prevent unnecessary questions. Eye-catching, these colorful flags are easy to spot and have a removable adhesive allowing them to stick securely, be repositioned and remove cleanly. The handy detachable cartridges can be used as a stand-alone dispenser or placed in a desktop dispenser/organizer with a built-in Post-it Flags dispenser.
