Fluorescent UV Marking Products by Sirchie

Invisible/colorless in normal light. Glows bright blue in UV blacklight. Please note, these markers do NOT glow in the dark. You must have a blacklight to get the glow effects. Extra large body with broad tip. Contains twice the ink as our standard sized markers! Safe for use on skin. Use for security marking (such as admissions) or create amazing invisible body art designs that glow in blacklight! These are the markers you want for semi permanent invisible marking.
