Invisible Ink for Marking on Skin - 4 oz. Got an event coming up where you need to know who has already paid admission? Many people don't want a visible mark on their hand letting friends and co-workers know where they have been. Invisible ink is the safe and easy answer!

6330 Invisible Ink is safe for marking hands for the purpose of admission to nightclubs, dances, sporting events, strip clubs, prisons or craft fairs. 6330 Invisible Ink can also be used on plastic for security purposes.
