I found that these pens write smoothly, but many malfunctioned almost immediately after initially using them. I like the ease with which they impart impressions and found that they remained fairly tight sand did not leak. The cost varies considerably, so shop around for the best value. With the malfunctioning pens, some I could restore to functionality by dipping in boiling water and then pressurizing them at the end opposite the tip. They develop air gaps and the ink needs to be compressed in order to function. They also don't last very long with prolific writing, but the ease with which they write sort of makes up for that.

I was extremely happy because I finally found a pen that I love, its incredibly smooth sharp lines and like high price fancy pen. I could not find this value at any local store or office supply houses.
