BLACKLIGHT GLOW Permanent INVISIBLE INK UV Black Light SECURITY MARKER Spy Pen
UV MARKER INVISIBLE INK MARKING PEN PROFESSIONAL VERSION III BLACKLIGHT ULTRAVIOLET U.V. High quality, EXTREMELY PERMANENT INK
U.V. ink lights up brightly under any blacklight, But can't be seen in daylight or room light Unlike most UV pens, this stuff is very, very hard to wash off Works magically on: Metal, glass, plastic, fabric, paper, wood, rubber, ceramics, and a long list of other surfaces
Pleassssse note: Not for applying on skin.
You're getting premium solvent-based ink, vs the more common water based UV ink. Typical invisible UV ink and ink pens, being water based, are designed to rub off easily. Not this ! You can get it off skin with a bit of work, but it'll take some religious scrubbing. This wondrous little pen can be extraordinarily useful over time, and may pay for itself many, many times over if it helps you catch a fraudulent online transaction, or retrieve stolen personal items. It's filled with a proprietary ink formula that won't leave a trace, and is completely undetectable by the naked eye.
Writes smoothly on virtually any surface- Secretly mark a liquor bottle if you think someone (kids, for instance) is drinking from it - Invisibly mark where an object, door, etc is resting: it it's been moved, you'll immediately know .
Know for sure that the new mechanic you're using actually replaced a part: simply mark your old one before repairs begin (and ask for it back) EASILY MARK YOUR STUFF IN CASE OF THEFT
Smartphones iPads iPods iPhones PDA's Purses Wallets CD's DVD's Industrial manufacturing, marking and coding Laboratory testing Teaching / student demonstrations Science experiments
Kid detectives can write secret messages, draw spy maps for their friends. Take notes you don't want other people to be able to read. Mark returned items if you're an online seller. Write computer passwords in invisible ink.
QUESTIONS FROM PAST BUYERS
Question : Hello, this really seems so neat. can you put this on clothing and then wash it without it coming out or fading all over the material ? Thanks so much, Angela Reply : Hey there Angela ! Yep, will work just fine on fabric, and can't say that with 100% certainty on all the many types of fabric out there, but it's quite unlikely it'll wash out of anything. Hmmmm.....maybe it'd fade over a hundred washings, but again, not likely by very much. Your best bet maybe is just try one pen only and experiment so you get a better idea of real-world results. Do keep in mind, too, that some natural white fabrics (cotton for instance) already contain UV phosphors in the weave (which is why some T-Shirts glow in a night club). Same thing for teeth. Sooooo.... UV ink won't show as well on white cotton.
Question : Hi, I recently purchased a handheld black light, a keychain black light and a black light pen from you. I just tried out the pen on regular paper and it doesn't seem to work. Thanks, Frank. Reply : Nothing wrong with your pen at all, as it turns out. I wondered how this could be, so ran some tests here, and realized something fundamental. That is, that some type of white paper (though not all) contain natural fluorescent phosphors (present in cotton, also in white t-shirts, your teeth, etc, which is why they glow under blacklights at a party). As a result, the invisible ink itself becomes invisible on bright-white phosphor-containing surfaces because the entire surface itself responds to UV, so it's then impossible for the ink to stand out as there's no contrast (like a piece of white paper in snow). Consequently, it's not just this pen, but no UV invisible pen or ink anywhere in the world would be able to be used on white cotton-containing paper (like inkjet paper). I did try it on a variety of other colors and it works fine. Even on white cardboard. But on the white inkjet paper I used, it doesn't show, so you can bet that was cotton laced paper.
Question : I'm a seller online and think I am getting scammed by a few bad apples, so think it is time I started marking certain pieces of my jewelry. Hopefully this will help protect me." Thank ! Karen Reply : Should do the trick Karen, best wishes ! Question : Thank you people, the pen is cool James. Reply : No....... thank YOU !
