Opticz Jumbo UV Blacklight Reactive Invisible Ink Chisel Tip Marker Pen With Rechargeable UV Keychain Light
These Extra Large Jumbo Blacklight Markers use our signature blend invisible UV ink that is undetectable to the eye under normal conditions but glows brightly under black light. Each set includes 3 markers; one in each color and a rechargeable USB Keychain flashlight.
Use them for secret spy messages, admissions, escape rooms, glow parties or for security. Safe for skin when used as directed. Enjoy making unique and cool designs that will really pop under any Ultraviolet light or utilize for security reasons such as identifying your stuff or authentic returns verifications! Please note markers only illuminate in ultraviolet light; they do not glow in the dark. Please note this is security grade ink and it does not wash off easily.
This creative writing utensil features a felt chiseled tip allowing for thicker, more pronounced stroke application for highlighting. Or a more delicate and precise stroke for finer details and writing. Extra Large Marker houses 2.5 times more ink than our standard-sized marker for increased longevity and value. Rechargeable Keychain light with Micro USB cable allows for effortless charging anywhere.
