A wooden hanging sign / door hanger with a stop sign design. Keep your family members from disturbing you in your room with this fun and quirky sign on your doorknob! The sign comes with three interchangeable / removable wooden plaques with phrases: "Knock 3 Times," "I'm Sleeping," "Meeting in Progress," "I'm Studying," "Enter at Own Risk," and "I'm Out." Note that three wooden plaques are included, and each plaque is two-sided. Thus, there are two phrases on each plaque and a total of six phrases to choose from! The stop sign door hanger measures about 7.5 inches by 7.5 inches. The only notable flaw is a small chip in the wood in the back lower left corner, which could easily be fixed with wood glue or crazy glue. Made in Taiwan. I'm not sure of the brand, as this was gifted to me. Can be used by kids or adults!
