I needed a black thin permanent marker. As I wanted it to draw clip art. It just so happened my teeager had one.
I use this marker to draw thin lines to any picture that i draw and then later scan it to my computer for colour to make my clip art. I therefore need a cood quality marker to use and to make sure the lines connect with ease and I don't end up with thick lines to thin lines as that would make my picture look aweful.
This marker is waterproof on most surfaces and refillable. It is very easy to use and lightfast. I don't have to worry about smears with this marker. You can also use it as a permanent pen to sign papers as it is thin enough for that.
I don't know if they come in any other colors. But i'd imagine it does. The lid to this has a clip on it for easy clip onto any t- shirt pocket for easy access. You just twist off the end tip to refill it.
I am going to be going out to purchase one of these for myself as my daughter wants hers back. As she uses it for her paper work at school.
