- Secure owner information: three physical keys are included to lock and protect the owner's details so only authorized users can reveal or change the displayed numbers. - Simple, accurate number display: a twistable blocking rod lets you expose numbers precisely; the design sets the viewing angle to 19° so digits are clear and easy to read at a glance. - Strong, versatile adhesion: VHB Nano seamless paste provides a reliable bond that is washable and holds on both smooth and rough surfaces. - Durable, fade-resistant materials: the numeric stickers are digitally printed on PVC for long-term use without color change or peeling.
