Uv Light Creative Stationery Invisible Ink Pen

These pens were a great buy, I used them to address my wedding invitations on green envelopes! They showed up great and the post office had no issue reading them. I also used them in my cricut to MAKE my wedding invitations. I wrapped a small piece of duct tape around the pens to make them fit without an adaptor. I would totally recommend these!!

Used this for my in-home escape room puzzles. It is still working just fine after 6 months light use. Also bought a small UV flashlight for the escapers to use. The tiny light on the back of the pen does let you see what you've written, but its beam is narrow and a bit weak for use in the escape room.

I bought two of these, one for my 9 year old daughter, and one for my 7 year old son for their Christmas stockings. Unfortunately, one was completely dry when we opened it. However, I contacted the seller and in less then 48 hours we had a new one which works great! So far they've had a lot of of fun with them, writing secret messages. Anything that keeps them off the iPads is a successful toy in my opinion and these do it!

I love this simple pen. I have two now. I'm enjoying the extra fine tip. It's almost like writing with a ballpoint but so so so much better. I had to get out of the habit of posting—it's surprising how much of a difference the weight of the cap makes. It writes beautifully unposted. I would say it is my favorite pen, but if I'm being honest, my favorite pen is usually whatever I'm writing with at the time. So I guess I can say it is the equal of all of my other favorite pens :).

Some always fail, or dry ink very fast or the light doesn't look. But many come and in the end are great as they serve my work perfectly as well as being able to play with my son and friends. It's fun.

They work well, but I think it would be better if they didn't all have the light, with a light it's enough and more interesting than the marker lasted longer.
