​​The dispenser does not include a container for topping up. Cartridges are inserted into the dispenser - bags that are hermetically sealed and there is no risk of contamination of the contents. This dispenser includes bags of the GROUP system.

Simple exchange of an empty bag for a full one also saves time when refilling the dispenser. Literally in a few seconds, the dispenser is full again and ready for further use.

Thanks to the fact that the empty cartridge is thrown away without a dosing mechanism (i.e. only the bag itself), the system proves that even a cartridge solution can be environmentally friendly. This is because much less waste is created than when refilling from a canister.

The size of one dose is 1,4 ml.​
