You can get these for less.
This is over priced, you can buy them for 7-9 dollars less. I work at a tea shop and I have been using the same exact product with the Finum brand instead of the MSR one for years now to make coffee and tea on the trail and off.
BACKCOUNTRY.COM, please carry the less expensive and just as well made Finum filter. They also offer different sizes!!!!
