Premium 12 Pack of Paint Pens, Fine Point Permanent Oil-Based Paint Markers for All Surfaces and DIY Projects: Glass Painting, Ceramic Mugs, Porcelain, Metal, Wood and Fabrics. Water/Sun Resistant

My 90 yo Dad has a small hobby orchard. For years he has been looking for the perfect way to label his trees in a way that is easy to read and can withstand weather, rain, and sun. No previous attempts were successful, which included Sharpie markers, nail polish, engraving. I bought him these pens along with some tags and he is thrilled. We haven't been able to test them over time, but he thinks that they'll work perfectly. So far so good!

I got these pens to make mugs. The colors alter/darken a lot after baking. The black would not set at all - scratched right off. The tip of the blue one was broken. Boo.

Haven’t used it yet however so excited that I can express myself on so many types of material I bought one for my artistic friend and she loves them.

I just used the product and it works good. The lines are good, but be careful when you first start as it comes out faster than expected.

Not happy with these pens at all. The color changes and flakes off. Says I cannot return when I attempted. Would not recommend!

Can’t return this and a couple pen tips are busted from the package. One of them exploded all over me and the paper I was using. Hopefully it works better for others.

cant speak to how long they last but they work great so far. I use them for automotive work and they work great for labeling and marking parts.

These markers were perfect for the project I had in mind and have come in handy for other projects as well. I would highly recommend these!
