Invisible Ink Pen, Spy Pen with 3 PCS Mini UV LED Keychain Flashlight, Disappearing Ink Magic Pens with Black Light Markers for Secret Notes, Fit for Christmas Halloween Holiday Gifts (3 PCS)

We did a scavenger hunt and this worked marvelously! We absolutely loved the invisible ink - it showed up so well!Pros:- The pens work great- The lights actually show the invisible ink.- That are durable and last well- They are just so fun!!!Cons:- The marker tips are on the thicker side so writing small is not an option.- The ink does run if it gets moist or wet.This is a great price for the awesome item you get - I would highly recommend purchasing it!

The marker dries quickly on the paper, and appears bright with the UV light. I wouldn't use it for writing, but drawing art with it is fine. It's quality is good for the price, especially if you draw with invisible ink.

These are very fun for the price. I got them for a treasure hunt puzzle game with a group of children. The lights aren't very bright, but I was pleased that I got several for the price (and I already have a UV flashlight so it wasn't a huge loss that they aren't the best). The markers were all full of ink--none were dry. They show up nicely under the lights, especially the pink. My biggest complaint is the blue appears to be pretty much identical to the yellow? At first I thought maybe there was a mistake and the blue marker got filled with yellow ink when they were made, but the blue pen is also the most visible pen under natural lighting, so it seems to be different. All of them are a bit visible until they dry, but if you look closely you can still sort of see the blue marks hours later. I may have gotten a bad one. The other pens are great though! I definitely recommend these (especially if others are getting better blue markers), they're lots of fun.

Works really well. Markers are crisp and easy to read, but completely invisible without UV light. I used this for a work retreat where we needed a hidden code for an activity, then gave it to my five year old afterwards and it works great for both!

Perfect pen for secret messages!

Great for anytime you need to write a secret note that you don’t want someone else to see to a coworker or a significant other, etc.

If you're getting this for art, or drawing on yourself, go for it, it amazing, but if you want to draw in a book, or blacklight your journal three with it, don't. It bleeds through paper pretty easily. If you want to do that, I'd recommend erasable highlighters. It takes several minutes to fully dry, it's fun and decently bright. For what it is, it's worth the money long as you know it'll do what you're looking for

Bought for eBay store to lower electronics returns. Writes great on paper like items, but doesnt have that sharpie quality that can write on metal objects, it just wipes off.
