Are you working from home? Let everyone in the house know if you need privacy with this handy doorknob hanger! It's made from sturdy whiteboard with a chalkboard back so you can mark the appropriate check boxes with a dry erase marker (not included). The words are engraved and won't rub off.
The front of the doorknob hanger says "Hi! I'm Working." with the following options: Do Not Disturb, Knock First, or Come On In. There's also a space to fill in a time for the end of your work day.
Works great for students, too!
The door hanger measures about 8.25" by 3.25".
