It's none other than Sharpie, perhaps (or most likely as far as I'm concerned) the most famous brand when it comes to markers. You have a girl sitting next to you in your college class who just so happens to need a marker to finish up "the task" ask you, "Gotta Sharpie?".
This marker by Sharpie in particular gives you a fantastic bold output upon using it on things such as CD's/DVD's (discs - which is what I mainly use it for and above all bought it for), paper... the list goes on and on as far as what this marker is able to produce ink on and keeping it there for that matter, hence the name "Super Permanent".
A comfortable grip comes along with this, so if you ever happen to get bored, you may find yourself writing on more things than you had expected initially, so don't say I didn't warn you! Even though the marker was more made for industrial use as suggested in the title, I still prefer these over the regular ones but that's just me, due to the boldness (not really a fan of extra fine point) of the marker. But above all, if you're looking for something that'll come off as rather too strong in terms of ink when compared to other markers, then I think it's safe to say that the search is over!
