Don't take this serious without reading!
I made a mistake and bought these instead of the Falcon filter rings for the older Falcon pipe, since it was my mistake I ate the screw up but decided to try them in my other pipes that take straight filter, wow that was a mistake, these filters have a bad odor when the get hot and ruins the tobacco your smoking at the time, ruins the pipe to the point you have to really clean it good and not just the pipe cleaner through the stem routine! Not sure if these are better in an International Falcon but I know they won't work in the older Falcons that call for filter rings and they SUCK in normal pipes! Good luck and would love to see a review on these from someone with an International Falcon.
