The SodaStream Hipster Fuse Bottles 1 liter 3-pack allows you to make enough fresh soda water for the entire family. The bottles each have a 1-liter capacity. The print on the bottles makes it easy to remember which bottle is whose. The bottles aren't dishwasher safe, so you need to clean them by hand. Because of the constant, high carbon dioxide pressure on the bottles, you shouldn't use the bottles after the best before date has passed. The best before date is printed on the bottle. These bottles are only suitable for the SodaStream Spirit.
