    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.

    BITS OF TRIVIA :
    Apparently part of the plot of the movie 'Da Vinci Code' involved the use of a UV marker.
    And, in 2002, a multi-prison uprising was organized using UV markers. Uh oh.
    QUESTIONS FROM PAST BUYERS
    And, just maybe, a few answers
    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

    :
    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
