Invisible Ink Pen, MALEDEN Spy Pen with UV Light Magic Marker Kid Pens for Secret Message and Party Goody Bag Stuffer (6)

Product Information

Ultraviolet marker pens use ink which lacks colour pigment, so it doesn’t leave a mark visible to the naked eye under normal lighting conditions.

Personalised items will have to be produced first, which can take up to 4 business days depending on the item. Your secret message written with this pen will be invisible to the naked eye - It can only be seen with the UV Light. This includes anything that’s made to your specific requirements, is personalised or otherwise can't be resold due to a bespoke element, Perishable products (like food or flowers), or Personal items sold with a hygiene seal (like cosmetics or underwear) where the seal is broken. Please don’t destroy or throw away any product, even if it’s faulty, before you’ve spoken to the us and agreed that doing so won't affect any refund you may be entitled to.For deliveries to the Rest of the World, Royal Mail suggests up to 21 working days for parcels to arrive. The top layer of the ink will be removed if you try to smudge it with a wet finger or a wet brush - we have a blog above which has a test of 7 Black inks and has a video showing any surface run off from this and 6 other inks.

Nathan says it is the ultimate battle between man and beast and your bank balance and social standing have no bearing on your ability. This is right at the edge of the visible light spectrum, so you will see a purple glow cast from it, but it is a long enough wave to excite the fluorescent material and reveal the secret message. To the normal eye it will look like a blank piece of paper, then use the other end of the pen to shine the UV pen on it and the secret message is revealed. Nathan Tardif is best known for his political views and historical knowledge, which often spills over into the names and labels of his inks.Keep in mind that anyone can view public collections - they may also appear in recommendations and other places.
