Customer Reviews

Purchased these markers for marking lab tubes for blood and specimen containers. I needed these "industrial" markers because the ink from same-brand, simple "permanent" markers would bleed when not given enough time to dry and were exposed to liquid. These "industrial" markers are minimally more expensive than the same brand "permanent" markers, yet far superior in durability of ink. Regular permanent ink is soluble in non-polar liquid (acetone) even when dry, and requires a measurable dry time to set before being insoluble with water. Draw width is only slightly wider than a ball point pen. These markers are perfect for any application requiring solid, fast professional marking where truly permanent ink is invaluable.

I have looked high and low for these anywhere and everywhere since I taught school and you can't buy them! I was so relieved to find them! Shipping was extremely quick and they were exactly what I was looking for!
