My Grandchildren Loves Them

I bought the MaleDen Invisible Ink Pens for my 4 grandkids and they all love to use them to write secret messages (mostly on my arm). I have to admit, at 66 years old I kinda' like using them, too.

Great deal!

Great deal, all pens had the pull-out sticker that keeps the battery from draining so that was nice. My son is going to be thrilled for Christmas!

Black Light Party!!

We used these to decorate for a black light party. They worked well on different surfaces, including skin. I know it's my bad for not fully reading the details, but I thought they would all glow slightly different colors (based on the color of the pen). Nope, they all glow the same. Still loved them!

Great for Wedding RSVPs

Used these for our RSVPs for the wedding. We were able to ID several RSVPs that came back with no names on it. They would and are invisible!

Multipurpose

We gave these out at my daughter's birthday party as favors. The kids were all super excited and wrote all over themselves. I like to use mine for marking the walls for hanging things because it doesn't leave a visible mark. We ordered two sets and all of them worked although a few took a little tinkering.

A++++

They're awesome. Really worked out great for us. We used them for our wedding invitations so we can number everyone's return card incase they didnt put there names on them. We knew who it was

Great pens for the price!

I bought these pens to use with a girl scout troop. They arrived quickly, are brightly colored (a plus), the ink actually dries invisible, which I've found not to be the case with some others. The lights all worked on the pens I received, so no downside at all that I've seen so far.

Worked perfectly

These pens were very nice. Packaged well. Gave them to nieces and nephew for Christmas. Pens even write on skin and you can't see the writing until you shine the lighted end of the pen on it. Children I gave them to were 6, 7 and 10. They all loved them.

Wedding Invitation Saver

I bought these to discreetly mark the back of my wedding RSVPs with numbers in case someone replies and forgets to put their name. I have heard horror stories of this happening and while I was given the idea by a friend I didn't want to use a pen or pencil that was visible to the invite recipient. I tested the pens on various pieces of paper in different colors and when I used the light I could clearly see what was written. I'm looking forward to using them on all of our invitations and know who responded even if they forgot to write in their name.

Good deal, fun pens

I actually bought these for making hidden areas on dungeons & dragons maps. Not exactly what they were intended for, but after creating the maps and then using them in a game about three to four weeks later, the ink still appeared when the light was shone. They are a unique item I believe could have many creative uses, and they're very affordable. Would highly recommend.
