BONNYCO Invisible Ink Pen and Notebook Pack 16 Dinosaur Party Favors for Kids, Magic Spy Pen Goodie Bags Stuffers for Kids, Dinosaur Birthday Party Supplies, Goody Bag Stuffers Return Gifts Prizes

Loved this for my daughter birthday goodie bags.

Such a cute idea for a goodie bag. However, I ordered 32 of these, and only 13 of the pens worked (the light).EDIT: After leaving this review the seller reached out to trouble shoot and wanted to replace the order. The event I needed them for had passed so they actually refunded me for both boxes even though I had handed out the pens that did work. Excellent customer service. The message they sent also said there is a way to get all the pens working, though I did not get a chance to try it:“Please be advised that the pens are not working because the batteries have not made contact with each other. But don't worry, this can be solved. To do so, follow these steps and your pens will work properly. 1- Re-insert the white plate and make circular movements with it, trying to move the batteries slightly. 2- Remove the white tape and check that the pens work correctly.”

The kids from age 2-9 all loved playing with these at Easter and for days to come. one of the lights didn’t work but for the price I thought that wasn’t bad at all. Hours of entertainment!

I always use a detective theme with my class each year and try to find a similar themed gift for their holiday gift. This spy theme was close enough in my opinion and knew it would be fun my students. I did read a lot reviews so I knew I would have to check each one out and may have some or several that didn't work. Out of 36 only 2 lights didn't work (of course the first one I tried didn't and I then was concerned - I did follow the directions & it still didn't work.) Then I tried the ink and all worked, but 2 of the tips were slightly bent and their ink was faint. Also, the caps were tight and should loosen with use. I explained that to my students so they could get their parents help. I only needed 24 sets so this left me with 32 good sets. I have some spares to give to friend's kids. The packaging was nice and matched the notepad. I am pleased with my purchase and even better so were my students. 🙂

Excelente compra

Gave these out as stocking stuffers, and the kids loved it. My daughter loves spy kids so I knew this would be a hit!

My son loved these. The pen works, the light works, zero problems. And they were a huge hit at his birthday party and I will be repurchasing for future parties…. No matter the theme, what kid doesn’t love INVISIBLE INK? it’s the perfect unisex party favor. Get it!

We gave these out as prizes and also used them in a scavenger hunt where we wrote the clues with the invisible light and each team was given a pen and they had to use it to read each clue! Everyone of all ages Loved it!!
