Permanent Markers

Precise marking pens for short lab samples, slides, beakers, sample bags, and more. Write on glass, film, synthetic, metal, earthenware, wood, rubber, and paper. Permanent ink dries in a split second and is water- and fade-proof. The airtight ring seal cap restricts dry-out. There are other varieties of markers where you can erase the ink after work, known as dry erase marker.
