## Questions & Answers

**Q: what type of battery does the light take, and is it replaceable?**
A: I've never needed to replace the battery, but when I opened it up, I found a battery that says, "LR41 +soda AAA button cell".  I don't know if that helps.  It's definitely not a standard AAA battery.  It's much smaller than that.  Even if you can't find the replacement, I believe it's the pen, and not the black light, that is special.

**Q: Does this work on T shirts?**
A: Yes. This type of ink adheres best to textured surfaces. A fabric shirt will work just fine.

**Q: Am an artist and like the idea of signing twice, BUT, Can this be removed if necessary?**
A: I don't believe you can remove the ink.

**Q: Is it outdoor permanent ?**
A: This marker is great! I have the same one I bought 2 years now and I use 40 times a day and bit frayed but still inking it. I sell vinyl records and mark all my records with this. I don't know what your.using this for but I have never tried to wipe it off I'd you put it on skin I assume it will wife off. I use it as a permanent marker On my records

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works well
*by L***N on October 20, 2025*

Works well to mark items I resell. Good theft deterrent.

### ⭐⭐⭐⭐⭐ Worked very well and a good price
*by F***O on June 23, 2025*

This little light and UV ink pen worked well for what I needed it for.

### ⭐⭐⭐⭐ Fades a little
*by Q***A on March 5, 2023*

I used this on top of an acrylic painting and it worked pretty well. The first picture is the first day (the plant on the bottom right had been done the day before and I redid a couple of the lines, so you can see the older stuff had already faded there) and then the next is two days later. It faded a little but is still visible. I hope it won’t fade more. It could also be because it was on top of paint. ETA: It does fade pretty much completely after several months; I haven't checked exactly how often, but I've typically touched it up once or twice a year. The black light it comes with is very bright, which was surprising for such a small keychain light. I actually wrapped a little bit of cardboard around it so it wouldn’t hurt my eyes when I use it.
