Unfortunately I don't know that either, but I would be interested in GALAXUS. Should be available as an accessory! Otherwise you would have to make do with another, non-device add-on, which would be a shame.

No, I don't know.

Just buy Ha(ns) Ra(ab) (concentrated full care), Ha-Ra (yes, that's the name of the PRoduct). Plant-based raw material, 99% biodegradable. A classic in Switzerland.

Just 2-3 DROPS, put in water container, et voilà.

The 40ml vials contain poisonous chemicals. Read the warnings on the vial.
