Get your old pens working again- tip

This isn't earth shattering tattoo info or anything, just thought it might be helpful. Say you used a nice new pen on someone, and now it doesn't work? Or you have an old pen that seems dried up? This was bugging me so I got a lighter, and put the tip of the pen in the flame for two seconds, then immediately scribble amap to get ink flowing.
Yet to see this fail =]

Heat expands the metal tips. Ink gets thinner.

I just use pens once... And throw it away. Problem solved.

Plus the pen prolly stops working cause there is bits of people's skin and oil and nasty bits all up in it.

is that basically what those "specialty tattoo skin pens" are?./...just regular ball points but with thinner ink?
