Very cool ink.
Still, I'll much prefer these friXion pens over the new Sharpies since under normal usage, writings usually don't get exposed to tremendous heat. So to me and perhaps normal users, these friXion pens are more like erasable pens since they are not subject to the 3 day rule the new Sharpies impose.
The only question remains is if these new Sharpies' "liquid graphite" writes like a real pencil, in which case, it would have a totally difference use and market (art, drafting, etc.). Since it says it's available already, I'll probably grab some and find out for myself. I'm cited!
