Le Mark ProGlow Tape 20mm x 10m – Green

Pro Glow has 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 photoluminescent film 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, Pro Glow film temporarily emits a light of its own.
