DLUCKY Invisible Ink Pen,Spy Pen Invisible Disappearing Ink Pen with Black Light Magic Marker for Secret Message and Kids Party Christmas Halloween Easter Goodies Bags Toy 14Pcs

I bought these for my 7-yo granddaughter to use in her journal. The invisible ink with the black light was a big hit! She has shared some of the pens with her best friend which makes them really special.

These pens are so cute! I bought them as favors for my kids' escape room birthday party. I didn't open all of them to see if they work. I will wait until closer to their party. I did try one and the ink is almost invisible on white paper and white foam. It leaves a wet mark on cardboard and a dullish look on magazine paper. It didn't bleed on any surface that I mentioned. The light is real black light and made the ink glow brilliantly! Im am very happy with these pens.

Ordered these for my sons who wanted so desperately to be spies! I found that this engaged them in writing and helped with OT and dysgraphia as they wanted to right and it wasn’t a fight. Now was it a full proof solution no but every little bit helps. They are also well made better than the previous ones we purchased at our local book store. The ink hasn’t dried out and the lights are all nice and bright.

The kids have enjoyed them. They aren't the highest quality but good for the price. It's been fun for them to play with.

The pens seem to work fine, but I wouldn't suggest them for younger kids simply because the caps for the pens have to be really pushed in hard for them to actually close fully. I have a feeling they are going to dry out quickly because no matter how many times you tell kids to push hard on the caps until you hear them click closed, it's most likely not going to happen

My kids loved it . They sell a similar pen at school for 2$ each and they leak, so I was hesitant but my kids enjoy them and these were more affordable ... but these don’t leak and there is so many for pens you get for the price.. my kids have been giving it to their friends

All the markers I've tried so far work. I got them as prizes for my kids, and they love them.

I got these for goody bags. They are so cute and feel good quality.

Merci les enfant on bien aimer

The media could not be loaded.  Super crayons secrets pour les détectives!!! Les enfants adorent je vous les recommande!!

Kids and adults...who doesn't LOVE a spy pen?!? This is excellent!! You write on skin/paper and it kinda/sotra fades as the days go by...which is absolutely perfect! I would buy this again in a heartbeat. Thank you!!

Bought these for my students. 6/14 didn't work.

They seem cheap in the picture but they work like a charm and that is a what matters. My kids LOVE writing secret messages and then revealing to one another. We gave a few to friends so the littles can have fun being spy pen pals.
