SpyXInvisible Ink Pen - Write and Read Invisible Messages with This Fun Spy Toy. Perfect Addition for Your spy Gear Collection!

I got this to go along with a notebook for a spy themed gift. I hope they enjoy it and that it provides some fun and mystery. It was perfect to go with a spy theme.

Fun, impactful stocking stuffer! Works as advertised

Don’t bother with this - arrived completely dried out and does not function in any sort of manner that it should. Mine did some with batteries but also only worked if you pressed the button juuuuust right. Regardless we had no ink to look at…

bought this as a gift, great idea, unfortunately the ink was dry and didn't work very well. Not a good result for a pen...

The SpyX Invisible Ink Pen is a must-have for any spy enthusiast or anyone looking for a fun way to write secret messages. The ink is easy to apply and dries quickly, and the included UV light makes it easy to reveal the hidden message. Great quality and a fun addition to any stationery collection.

Cool... got it for a 6 year old who is into playing spy now... works fine as described...

The marker doesn't dry out quickly, the UV light isn't too strong, and the pen can withstand some abuse from an overactive child. I would recommend anyone to purchase this. If we ever needed to, I know we would.

my daughter loves it.
