Tagged Stamps

The material has been prepared by Alex Barinoff. Ph.D., CEO, Founder

Tagging the stamps with phosphorescent coating allows them to be easily seen under shortwave (200-300 nm (nanometers)) ultraviolet (UV) light. When tagging is exposed to strong shortwave UV light, tagged stamps glow a bright color that ranges from yellow-green to bluish green.
