Refillable 16-gram Food Grade CO2 Cartridge
CO2 cartridges have traditionally been sold as disposable units. Did you know that from a bulk tank 24-inches tall, it only takes a nickel's worth of CO2 to fill a 16g cartridge? But most consumers still buy disposable CO2 cartridges! Why? It's simply a lack of options. Cartridges are handy. They're small and portable. They fit easily between the handle grips on pellet pistols and BB-guns. In fact, a host of products have been developed and sold, all made to fit and utilize these cartridges. Have you considered the energy required to melt steel, roll it into sheets and draw it out into little test tube sized bottles solely for the purpose of holding a tablespoon of CO2 that gets used up in moments, then thrown away? Would you throw away a spoon after each bite? It makes sense to put single use cartridges on life vests where you hope they'll never have to be used, but not in something you know you're going to use over and over.
It's your nickel. Spend it wisely.
