EODVICS 7 Pack Invisible Ink Spy Pen with UV Light Party Favors for Kids | Spy Gear Pen for Secret Messages & Treasure Hunts, Birthday Halloween Christmas Stocking Stuffers for Boys Girls Ages 3+

Great for kid's parties. They work, and the kids love them.

Welcome Traveler to the realm of Amazon; we have many years but this one in particular may catch your interest. What is it you might ask? Haha Well we have here is a pen that uses invisible ink but can only be seen in a special light. These are cool! I figured I would have some fun and add some depth to a campaign by writing hidden messages with these pens. The players can keep the messages as a momento for the campaign. They are good quality pens; take your time like any other pen if your rush you can smear the ink. Though id does dry up relatively quickly depending on the environment you are physically in. Haha. The functions like any other; I would suggest to buy a black light. Like any other invisible ink pen if you look closely enough you can see what is written without the black light. They are cheap; but personally think they are worth the money. Especially if one of your players ends up find one during their quest. Well farewell traveler; Be safe on your adventure and thank you form coming to the Amazon realm.

Purchased these for my 10-year-old imaginative grandson. He LOVED writing secret messages with them, revealing with the blacklight feature. Great fun!

I purchased these to go with some books that I purchased my grandkids that used UV light they are perfect for what we need them for I cannot comment on the larger yet because we have not used them the law periods of time. However they are very simply made so be careful with the switch but they are cheap so you get what you pay for

My granddaughter loved the pens. She can write on something or someone and then the light on the pen shows what she drew.

Great for secretly marking electronics. Works.

These are for a gift. I tried one. It worked well. Fun item.

Excellent. Very good quality. Highly recommend.

Kids love these, work perfectly. Perfect as a party favor (the ink is always the same color - invisible - even though the pens are different colors)

They do last long.Very smooth.The light doesnt run out quickly.

Vraiment cool et ça fonctionne très bien 😎

We bought these to add on to their Valentine's at school instead of candy. Happy with the quality of them for the price (although on a couple of them the switch to turn the light on was finicky). Would also be good in a goodie bag. The kids love them!

Added then to birthday loot bags. All of the kids loved them
