## Questions & Answers

**Q: How big is the tip of this size?**
A: It's about the size of a normal Sharpie. It's not fine but also not wide. I've found I can get corners done by getting close and letting the color sort of bleed into the corner.

**Q: Is this a paint marker?  I need to write on black plastic.**
A: Yes it is a paint marker that marks and flows on just about anything. Best markers I have ever used and does not dry out or clog like most do. Even good on a rock!

**Q: Can anyone tell me the size point for outlining. Smallest point Posca makes?**
A: Extra fine. 1 M. Still not super fine, but it's the smallest they make. I use it for rock painting and it's awesome for outlining.

**Q: Will this paint be waterproof on glass so it doesn't wash off in rain or snow?  I want something that needs to be scraped off if I want it gone.**
A: yes water proof.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Fun to use
*by S***N on December 27, 2025*

Good pen

### ⭐⭐⭐⭐⭐ Reliable
*by B***Y on July 30, 2025*

I’ve tried many pens for rock paint, but Posca pens are my favorite.

### ⭐⭐⭐⭐⭐ Doesn't fade in the sun. Good for plant tags.
*by J***T on January 11, 2020*

Last year, I purchased two blueberry plants. They came with a tag with the name of the varieties, but these faded away after a few months. I rewrote the variety name with a sharpie, but that also faded away after a few months. In the end, I forgot which variety the two blueberries were. This year, I am rooting 40+ fig stick cuttings in my basement with 13 or 14 different varieties. I can't afford to have the same thing happened to me. On several fig forums, I was told that they usually write the name of the fig varieties on the stems. I asked about the same issue of fading away and was told that the normal sharpie pens tend to fade over time. The same goes for most of the paint markers we find here in USA. A well known fig collect recommended this pen saying that it doesn't fade over time, so I got it. If you are using this to mark plants or tags that are outdoors in the sun, this might be the best option. The ink flows well and is a nice opaque white. The pen I bought was shipped in from overseas (Japan?) so it took quite long to arrive. Take note of the shipping time before purchasing. That said, for a pen that is shipped from half way around the world, it is not expensive at all.
