I use this marker in art class for pen and ink projects and while I like the product it does tend to have more of a blue tint to the black which can be a bit annoying when you are trying for a true black and white image.Art teacher Steve
Over the last couple years we have bought both Marks-ALot and Staples brand my forman just came up to me and stated he only wants us to buy the Staple brand markers. He said they not only out last the name brand buy 3 to 1 but the tip stay strong to the ink is gone. He said somethins he has to throw away the name brand before the ink is used because the tip is no longer servicable.
