Exactly as advertised. Replacement for the Hart double twist. Not sure why someone would rate low if the were looking for something different. Duh!
It is frustrating not to list the length of the replacement tubes. They are not listed in the pen instructions nor on the replacement tubes. Are they the same as the American Classic? What about other O pens. By withholding this information you make it difficult to mix parts.
