I've found that you can get the ink from a cheap pen, such as a Uniball Gel
Impact RT (which you can find in bulk at any office supply store or Wal-mart),
fits the casing and the opening of this pen perfectly--although I must say that
the ink from the Impact RT is much more runny and thicker than I would have
liked. It beats expensive refills!
