If you have a message you'd like to send out to people before they enter your room, scribble it on the very quirky Chalkboard Door Hanger.
The Chalkboard Door Hanger is like one of those "Do Not Disturb" tags used in hotels, only users can actually have their way with it. The item has a double-sided blackboard that allows people to leave personal messages, reminders or any other important notes. The top has a large perforated hole that will hang on any door knob. Whether it's "Keep Out" or "Dinner at 5pm," this will prove to be a useful accessory when it comes to making a point.
The Chalkboard Door Hanger comes with an eraser and two pieces of chalk.
