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+

These work decently well, and the multi pack was great as favors for my kids birthday! I even used one to mark their treasure map to add extra challenge and fun. Every kid loved them, and they got a lot of use on our birthday camping trip!

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.

So much fun! My grandsons LOVED these! What a fabulous “adventure” gift for them!

Got these for my girls after I refused to buy one from the school book fair for $6.99. What a Scrooge I am… I know. But these are an incredibly awesome value. They function and perform just like the real deal. They are super easy to use and are great quality. Love that there were so many different color options—all three of my girls were more than happy and each got multiples. It’s been months, and we still use and get a kick out of them. Definitely would recommend them to anyone. Such a fun little pen/marker. My youngest is 5 and my oldest is 7. They all love them.

Write well and light was small but worked well. Due to small size could only read a few letters at a time.

Great for secretly marking electronics. Works.

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

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.

Bought for birthday goodie bags. These are such great quality! I read the reviews and didn’t know what to expect but I am so highly impressed at the bright light and durability of these pens. Would recommend to anyone!! 20/20 will but again 😊

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!

Vraiment cool et ça fonctionne très bien 😎
