Review: Invisible with normal light, works great with black light! Love them!!! - These are great! We used them to label the back of each wedding RSVP with a number so we could figure out who it was from - in case of hard to read lettering and/or they don’t say who it is. Once the ink dries I couldn’t even see it! And with the light provided it was easy to see! Highly recommend if you want an invisible ink pen that’s at a great price!!

### ⭐⭐⭐⭐⭐ Love using these.

Fantastic colors and pens. The keychain lights are a little disappointing, though. But, those aren't why I bought these.

### ⭐⭐⭐⭐ Pretty good for under $10
*by B***A on August 19, 2026*

I wanted to mark some game pieces to make it easier to find the matching cards, but not ruin the look of the pieces and these pens were perfect. The yellow was a bit weak on the wood, so I just used the pink and blue. The blue had a slightly thicker point and more even coverage, but the thinner pink proved useful for the longer names. On paper, the blue was still the brightest in the black light, but it was visible in regular light. The yellow looks great at first but then fades into the same color as the blue under black light. After ~5 min of drying, you could still see the blue writing, even though the others fully disappeared. These could be fun for other things if you didn’t need the three colors… As a side note, at work, our props department uses something similar to these to mark liquid levels or placement of specific items that actors use, so we can make sure we start in the same place when we do another take. That said, if you need to make sure your roommates or kids aren’t getting into something they shouldn’t, you can mark it with these! Would buy again.
