where are they manufactured?

There is nothing listed on the package to indicate where it is manufactured.

Is the hr-100tm ink roller compatible with casio hr-170rc model ?

I have a Casio HR 100TM, don't know if the ink roller will also fit the HR 170rc model

How long does a cartridge last typically?

It greatly depends on usage and it is very subjective as to when the print is "light" but I would estimate a few months on average is a fair estimate for medium use.
