Shhhh... pass this to Lilly...
Cute gift for my 7th grader and her 4 best friends. A positive thing about the no cell phone law in schools (Texas) is that these kids have to pass notes 80's style again. Yay for hand writing practice! This way they can write their secret messages and not have them read out loud in front of the class without the super secret spy pen (cuz maybe Ian really is soooo cute but you don't want him to know you like him). Ink dries quickly, light works great and has a plastic damn in place to preserve the life until youre ready to use.

Great product
These are great for stalking stuffers or gift bags. Easy to use and fun. They’re compact which makes them easy to store. The pens seem to last a long time as well without drying out.

Better than the larger set I purchased.
These work well and the kids have fun with them.

Great for marking hard goods in my reselling business to cut back on fraudulent returns
I recently picked up the Invisible Ink Spy 5-piece pen set with the UV light, and I have to say, it’s been a game-changer for my reselling business. I needed a way to mark my items to help prevent fraudulent returns, and this set has worked perfectly for that. The pens write smoothly, and the invisible ink is truly, well, invisible until you use the UV light to reveal your markings. I’ve used them a few times now, and the batteries are still going strong, which is a relief. None of the ink has dried or leaked out. The compactness of the pen means it fits in my pocket. It’s super easy to use—you just mark your item, and when you need to check, the UV light brings everything to life. Overall, I’m really happy with this purchase. It feels like a simple solution that adds an extra layer of security to my sales, and I would definitely recommend it to anyone in the resale game!

Fun Secret Pens!
My granddaughters love these pens. They write secret messages to each other. The lights reveal the messages that they can only see.

Great
All my daughter wanted for Christmas was a "magic pen" since I wouldn't let her get an expensive one from her book fair. Tested them out before saving them for stocking stuffers and they are so cool! Honestly Works better then I thought they would! Very happy with purchase

Such a fun toy!
If you’ve got a kid that just LOVES to write on anything and everything, these are for you! The ink is completely invisible and the little flashlights on the pen make it really fun. Super easy to use, my 3 year old was able to work the flashlight to see her scribbles
