SpyX Invisible 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

While on vacation with my nephew, he had selected a spyX spy kit that included an invisible ink pen. He loved all the gadgets and we got so excited when we thought of me getting an invisible ink pen so we could write "secret messages" via post card back and forth to each other (we live about 2 hours away from each other). We picked out post cards and I ordered my pen. When it arrived, it was dried out and didn't write. I realize it's "invisible" ink, but because we had played with his, I knew how to check with the special built in flash light. I returned it in exchange for another. When the replacement came, the packaging had been taped together, indicating it had been previously returned - who knows, could have been the one I returned! It didn't write. I'm going to try and secure a different brand from a different seller. It's really disappointing to disappoint a 9 year old boy excited to write!

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.

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.

This arrived with little to no ink. It would barely write at all. Light worked fine, but I was unable to use it for the purpose I bought it. I didn't attempt a return/replace, because I needed it on the day I opened it.
