Uni Posca Marker PCF-350 Paint Glass Pen Brush Tip 8mm White

It worked well writing on slate

More of a paint brush than a pen. I was using to mark up my tools and the marks probably have to be redone every 3 months

It's fine. The colour doesn"t come out easily but i guess it's because it's new and need to be used to become more efficient.

This is definitely the best white "marker" to add highlights for a pencils. I'm using koh-i-noor polycolor ones as I love them for their pigmentation and the fact that they're easy to blend - but they leave slick layer on the top when drawing is over and a lot of my other white markers and pens worked for one drawing and than pfft, not usable anymore. Posca one is amazing, as it contains not ink, but paint in it - this is why I called it "marker". It's also great thing that when I don't like the effect on pencils I can easily gently scratch it to try again once or twice without any sign of it being there previously but if I don't scratch it fastly after applying it stays forever. You can also pat it gently with your finger or some sponge to make a nice blur effect. Wouldn't reccomend it for the beginners, as you have to have quite stable hand to use it just the way you want because of the brush tip. I'm adding pictures of one of my works with highlights made with posca marker on pencils. If you're tired of markers ending their days after one piece highlights - take posca, really, you'll be never disappointed to the end of the paint inside the marker.
