Inkzall™ markers are no joke (an uncompensated endorsement)

 This is an unsolicited plug for Milwaukee brand InkZall™ markers, which arrived on the market making two promises:

#1, the marks won't fade (I'm testing that in the sun vs. a Sharpie right this very minute - but it'll take a few weeks/months)

#2, they will make a permanent mark on almost all hard-to-mark surfaces which give other products trouble, the classic example being oily / greasy metal.

 So far I have tested Inkzall markers on oily metal fresh from the mill, rusty metal (not fresh) from the scrap yard, glass, and silicone rubber.

 I stopped there, because I ran out of surfaces which I've ever had trouble marking with a Sharpie, and the Inkzall does all of them.

 In all fairness, some markers do glass just fine namely, most solvent-based markers.  I've seen loads of markers that make clear marks on glass.

Wax was the one surface I thought would be hardest to make a clean, non-beading mark on.  Guess not... yeah, I couldn't remember the name of the markers - it has worn off of the two that I have when I made the photo...

 There is one other little feature of interest to those who wear hard hats: the marker's clip was designed specifically to clip onto the brim of a hard had neatly.

  Of course, the extra performance doesn't come for free: these things run about five dollars apiece, which is I think somewhere around twice the price of Sharpies. 

 I think they're impressive, but I probably wouldn't be using them if not for the fact I can get them at a discount. :)
