1 Gallon Blu-Rayâ„¢ Invisible Ink

Blu-Ray ink is a specialized type of ink that can only be seen under ultraviolet light. This unique feature makes it ideal for re-admission hand stamping at events like concerts, sporting events, and carnivals, where organizers need a way to easily identify who has already paid for entry. Additionally, Blu-Ray ink is commonly used for security stamping, allowing individuals to mark their personal belongings with a stamp that is invisible to the naked eye but easily identifiable under ultraviolet light. This can help deter theft and aid in the recovery of stolen items by providing a discreet way to mark and identify belongings. Overall, Blu-Ray ink offers a convenient and effective solution for a variety of identification and security needs.
