Invisible Ink Pen, Spy Pen Secret Message Writer with uv Light Magic Marker for Drawing Fun Activity Kids Party Favors Ideas Gifts and Stock Stuffer (24pcs)

I ordered these as favors for goodies bags for a 'mad science' week at school. I really wasn't sure what to expect, and I didn't hold high expectations for them. They are amazing little pens! We loved them. The students loved them!!! They really worked just as stated in the description. They had a bright little light. The ink showed up like magic. My kindergarten students loved them! They wrote their names and drew pictures as fast as they could. A few of them actually wrote secret messages. These were the hit of the party, and we had some cool toys in their goody bags. I would recommend them. They're great fun at a great price. I don't know how long they last because the students took them home with them. We gave ours away to other kids. I really feel that we got our money's worth at the party.

This is true to description of items. The ink works well and when you use the light it looks very clear and nice just as in the description. The smelly pens were okay but everyone liked these so much better. They even asked if they could have two of these instead of the smelly pen.

I bought these for a 5th-grade school party and they were a big hit., I was pleasantly surprised at well they worked for the price. I did discover there is an art to writing in ink that you cannot see but the kids seemed to have a ball writing messages to each other. I am not going to lie, I kept one for myself. Even at 46, there is something fun about writing secret messages to your spouse. I guess some things never lose their appeal. the lights are much stronger than I expected and while I don't know how they will last over the long run they were great for a kid's party.

Bought these to go in my granddaughter's birthday bags for her class and all the kids loved them.

I added these along with a small notepad to my daughters birthday gift bags. I tried each one as I unpackaged them, no duds. The girls were thrilled with their secret message capabilities. Winning

This was a great party favor for 7 year Old’s birthday party! Awesome for boys and girls. They were excited to write on paper and use the light to read their “spy” messages to each other. Would definitely get again. Probably great for kids age 6-10.

Great value for money product, came on time!! The children loved it and played with it foes hours. I was also able to write secret messages on their bags for the children to discover later. Would definitely purchase again!! Thank you!

Gave these out as party favors and they were a huge hit. Was definitely worth getting the ones that are packaged individually as there are instructions on how to use.
