Box of 24 food-safe mypressi-brand gas chargers to use with the mypressi TWIST. Each cartridge contains 8 grams of N2O (nitrous oxide--the same gas that keeps your coffee beans from going stale in the packet) and will make up to 4 double or 8 single shots of espresso, or up to 192 shots per box. That's just 12 cents per shot!
Built to a global standard that has been in use for over 80 years, the mypressi CHARGERS are the recommended brand for use with the TWIST.
If the mypressi-brand is not available at your location, you can also use the Whip-It Brand, BestWhip or iSi chargers in both N2O and CO2 variants.
