I love this refill....

I love this refill. I have it in one slot and the eraser refill in another --
How this works isn't clear right off and I threw out the first one because I
didn't know how to advance the lead. I assumed it was defective - You have to
click down on the grey tab to advance (the tab that sets the refill into
position.) The eraser works the same way. I did a video on it a few months
ago, if you'd want to see how to do it http://youtu.be/7IKO-jqJqPY
