Do Not Open Bathroom Door Hanger

Approximately 15 cm long and 5.2 cm wide, this door knob hanger is precision-sized for optimal visibility without obstruction. Constructed from robust PLA material, it withstands repeated handling and environmental exposure in bathrooms and other interior spaces. The single-sided layout displays only the essential 'Do Not Open' message — large, legible, and intentionally uncluttered. Installation requires zero tools: it slides securely onto most common UK-standard door knobs, including traditional round, tulip, and lever-style handles. Suitable for consistent use in residential bathrooms, office meeting rooms, hotel en-suites, and accessible facilities where quiet, dignified privacy signalling matters.
