Recently bought Duramark Permanent Markers for myself for home use. We usually use sharpie brand just because that was the only kind I was aware of. I'm really impressed with the duramark markers. They seem to write more smoothly and so far are lasting a lot longer than the Sharpie ones do. They are comfortable to write with. And they don't give off that really strong smell to them so I am comfortable letting the children use them. They are permanent though so I recommend watching children use them when they do. My daughter got some on her hand and it did take awhile to get it to come off just like any permanent marker. So to sum up the reason I like the Duramark the most is that it does not have the really strong permanent marker smell to it.
