Rose Brand's Glow Arrows have a non-radioactive chemical light source incorporated into a flexible vinyl film that glows in total darkness after exposure to artificial or natural light. The chemical light source is designed to absorb energy from any nearby ambient light such as fluorescent lamps or sunlight. Once the source of extraneous light is removed, it immediately emits a light of its own. There is no limit to the number of times this product can be recharged. Three to ten seconds is the normal charging requirement. It can be used to spike stages for placement of scenery, mark exits in dark areas, mark light switches, and thousands of other applications. Its flexible vinyl backing is conformable and easy to cut to size.
