Sharpie Extreme Permanent Markers, Fine Point, Black, 2 Count

from

I don't really know how "extreme" it is, but if you want a marker that will write on just about anything, it's a Sharpie. And the fine point allows you to write smaller.

from Linda

Lasts longer than the other Brands for keeping its Point

from elaine

loved it writing on Christmas ornaments.

from Christine

I use Sharpie fine tip markers for my work production art. The tips stay precise for a very long time and there's no smudging or bleeding. The black is perfect for my work, but the coloured Sharpie...

from Mary

they are the best and with the extra potent ink they are even better as long as you're careful not to mark up your good shirt or pants because it will never come out! But that's the point isn't it?
