Hooray. Non-smearing highlighters


Who hasn't experienced the agony of using a highlighter and watching the text smear.

Zebra Co Ltd of Japan reportedly solved this problem by released a highlighter that won't smear you ballpoint ink (see link). How did they do it? By adding added positive ions to the highlighter fluid that supposedly help the ink stick.

It sounds great. I wonder if they have patented it?

Update: According to their US subsidiary, Zebra will not be distributing this highlighter in the US.
