Invisible Ink Pen Stocking Stuffers: MALEDEN 6 Pcs Upgraded Spy Pen with UV Light Magic Marker for Secret Message, Kids Halloween Goodies Bags, Christmas Stockings, Party Favors Toy, Individual Packed

The pen set has brought a whole new level of fun and excitement to our family's games and activities. With six pens in the pack, my kids and I have been enjoying endless hours of spy-themed adventures and mystery-solving missions.The invisible ink feature is absolutely fascinating! The pens write smoothly and cleanly on paper, but the real magic happens when we use the built-in UV light to reveal our hidden messages. Watching our secret notes magically appear under the UV light never fails to amaze us, and it's like stepping into a spy movie.My kids have had a blast using these pens to create treasure hunt clues, leaving surprise messages for each other, and even creating their secret code language. It's been a fantastic way to keep them engaged and entertained, especially during playdates and rainy days indoors.The pens are compact and lightweight, making them easy for little hands to hold. The caps fit snugly, preventing any accidental ink leakage, and the pens are sturdy enough to withstand a bit of rough handling from kids.The invisible ink pens have been a big hit during Halloween as well. We used them to create mysterious goodie bag notes for our trick-or-treaters, and the kids absolutely loved receiving a special secret message along with their treats.One thing to note is that the invisible ink works best on plain white paper or light-colored surfaces. When used on dark or heavily textured paper, the writing may not be as clear or visible under the UV light.Overall, the invisible Ink Pen set has been a fantastic addition to our collection of creative tools and toys. The thrill of writing and revealing secret messages has sparked our imaginations and added an element of surprise to our everyday activities. Whether you're planning a spy-themed party, looking for a unique gift, or simply want to add some magic to your family's fun, these invisible ink pens are an excellent choice!

My tiny human is obsessed with these pens

Grandkids and I like these. I use them to put my information on all my electronics

My son got a pen like this from a book fair at school, and was crazy about it. I ordered this set, he was obsessed with it for a few days, then forgot they exist. So while I cannot comment on durability, I would say they were a big hit, and he seemed to love them, while he used them. Good value for the price!

I used to use these to write on my walls without getting in trouble. Works well and is worth the price!

Mine was so cool I took it to school. I’m eight years old and I took it to school and a lot of people like that. I didn’t let him have it. I only wanna have one a girl.

Good price and a lot of fun. Comes with instructions on how to use the invisible ink pens. Nice variety of colors and a good price. Fun for kids of any age! Great party favor.

writes very light. u gotta have the black light pretty close to see.
