Pilot Silver Metallic Permanent Paint Marker - Extra Fine Point (0.7mm) - 2-Pack (41600) - Ideal for DIY Crafts, Metal Marking & Industrial Labeling

I have a glass cutting bandsaw which has to use a lot of water to protect the diamond blade and to cut accurately. This is the only marker I have found that won’t wash off! It’s easy to use, line isn’t too thick so my cuts are pretty accurate. Highly recommended!
