Sanford's Permanent Sharpie fine point marker, in my opinion, is the best marker in the marker today, and I won't be switching to any different type of marker in the next century, no doubt!
Since my hand touched this "perfect" marker, I've been using it for anything possible, and it's basically a marker for anything, it writed on any substance that you'll try.
The marker comes in a range of different colors such as Black, Red, Blue, Green.
Writing is possible upside down which is a big plus (it gives you an option to write with it in space as well), writing on CDs, great on carton boxes, even on you're very own coffee mug at work.
The marker's downside is that it's a bit tough to hold for a long period of time, it isn't very soft and hurts my hand after a while of writing, so you have to have little breaks when writing, and the marker dries out quickly if isn't re-capped after a short while of usage.
