Picked these pens up to use at the pizza shop I work at. We needed pens that would consistently write on thermal receipts. The pen and ink work fine on the paper (they do not skip on the receipt like regular rollerball pens) but the fine point tends to tear the paper quite often. Would recommend a medium point as a better option in this case but the pens themselves are great to write with otherwise!
Purchased the .38 fine point version of these pens. They tend to scratch the paper rather than write smoothly. Ink is faint if they work at all. Now I know why the price was marked down...
