When it comes to 8g CO2 cartridges there is none better than the NTG. The care and precision manufacturing at the NTG factory in Tochigi Japan is world class. These are fitted with the patented safe sealing cap, a clever puncture cap that releases the CO2 in the event that the cartridge is overheated. No other cartridge in the world has this feature which is especially important if children are about. 10pcs per box, 99.5% purity.
