Security

PARTSNZ supplies a range of invisible security pens ideal for marking porous materials such as documents, paper, and fabric. Our water-based, permanent waterproof pens remain invisible under normal light but fluoresce bright blue under UV light, making them perfect for discreetly identifying personal belongings. Complementing these pens, our LED UV torch is useful for detecting lice eggs, bed bugs, verifying ultraviolet inks in currency and IDs, checking credit cards for security marks, validating hand stamps at clubs, examining artwork and glasswork for hidden repairs, and curing UV glue.
