Dr. Ph. Martin's Twilight Glow is a glow in the dark paint and blacklight paint for fabric that really works! This is made specifically for fabrics and it glows real bright. It adheres to every fabric as well as glass, metal, plastic, and wood. Dries waterproof. If you heatset it on fabric, it's washfast so you can use it on clothing that gets washed. It can be painted, airbrushed, sprayed, or applied with applicators. It can be used to illuminate anything in the dark: light switches, stair treads, etc. It glows from any light source! It glows very brightly from blacklight. Cleans up with soap and water and it's Non-Toxic. Great for kids! (very transparent, so doesn't look like much in the daytime)
