A UV security marker pen with high quality permanent UV ink that leaves an indelible mark and doesn't fade like a standard UV pen. Markings are invisible under normal light conditions and fluoresce under Ultraviolet Blacklight lamps. How to use tip: The ink from UV pens dries leaving a glossy mark which can be seen under certain light conditions due to the contrast differences between the ink and substrate being marked - this is easily resolved by dabbing the fresh markings with a tissue to remove excess ink, waiting a few seconds to let it dry a little and then rub it until the mark is no longer distinguishable. Testing with a UV lamp will reveal the mark. It's recommended to practice the procedure a few times on something you don't intend to security mark first to learn how much pressure to use to gain best results.
