About this Product
A small plaque, suitable for wearing (hot-glue a pin-back to it), that reads simply "If you can read this, you're too close." In Braille. (Grade II Braille, like grown-ups use, so it doesn't take up much space) Color the dots with a marker, or leave them and keep the whole thing more subtle.
