Mighty Marker PM-37 Industrial Bottle Marker When you need marks that stand out and last, trust Mighty X Marker by Mighty Marker. The PM-37 bottle marker uses an advanced xylene-free, alcohol-based formula that delivers the permanence and durability professionals demand—without the harsh chemicals. The 12mm dauber tip lays down thick, highly visible lines on metal, glass, wood, plastic, and nearly any non-porous surface. Whether you're marking lumber at a mill, coding inventory in a warehouse, identifying pipelines, or laying out construction projects, the PM-37 delivers bold marks that won't fade or wash away. With 45ml of premium paint, this bottle marker outlasts standard markers and keeps your operation moving. Reliably marks surfaces from -20°F to 130°F, and once applied, marks withstand temperatures beyond this range. For best results, apply to clean, dry surfaces. Every PM-37 includes a bonus replacement dauber, extending the life of your marker. Proudly manufactured in the USA. The same vibrant, opaque formula that makes the PM-37 an industrial workhorse also makes it a favorite among artists, sign painters, and muralists seeking bold, permanent coverage.
