This industrial permanent marker has super permanent black ink designed for industrial, laboratory, and commercial use. The ink is fade and water resistant, works well on all metals, and can withstand temperatures of up to 500 degrees Celsius. Ideal for marking, measuring, or adding temporary black in the impressions of stamped metal jewelry.
Great marker that does the job! Thanks!
This is what I use to darken my letters! Simple and strong. Stays on
I always use to use a regular sharpie to darken my letters on aluminum...but after everyone raved about this one I gave it a try and am glad I did! Letters stay black after tumbling and super easy to use!
This sharpie is great! I was using regular ones but heard good things about this one and thought I would give it a try. So glad I did! I definitely recommend it.
I have loved the enamel pen, but I love how well the industrial Sharpie stays put. It is super long lasting and fills in nicely
