Daemson 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)

Kids had a great time! Can still see the ink initially, have to let it dry a bit to be "invisible".

Fun to use but also helpful when secretly marking an item. Great price too.

Bought for geocaching. The pens work well.the light works but is not bery 'bright' I needed a better light to work with these UV pens.

Granddaughter loved it

Good quality

I really like how vibrant the colors look under the black light. And how invisible they are without it. I’ma school teacher, so I’ve used it for mystery writing activities and prefer fun activities.

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.

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
