The AVAVA Metallic Paint Markers Pens for Rocks, Ceramic, Metal, Glass, Halloween Pumpkin, Wood, Fabric, Plastic, Paper, Christmas DIY Art Crafts, Medium Tip with Quick Dry (3 Black+ 3 White) is exactly what I was looking for. I needed only white and black paint pens that would write effectively on whatever surface I could write on, and provide even, complete coverage without fading in the sun, or getting washed away by the rain. The ink in these paint pens has some serious staying power, and so far even being outside in the HOT Arizona sun, they still look the same as the day I used them. If you're tired of acrylic paint fading, chipping, or wearing off, these are the perfect paint markers for you, I was very impressed at the emooth, even flow of ink, and how easy it was to start the paint flowing from each marker without leaving any pools of ink are ink blotches all over my sign. I highly recommend these paint pens.
