Sakura Solid Marker Glow in the dark

The first marker of its kind that contains photoluminescent material in safety quality for simple safety applications in the dark. It can write, stay, and glow on smooth, rough, wet, or damp surfaces. Photoluminescent pigments are superior to novelties as they glow brighter after the same exposure. The brightness and duration of the glow marking can last up to 30 minutes, but it depends on four factors: a. the intensity of the light/energy source to which the marker is exposed, b. the distance of the light/energy, c. the duration of exposure for the marker, d. and the color thickness of the marker.
