Powder for teeth whitening and very well refreshing breathing, pleasant mint smell. Powder very fine grinding, well removes coffee and tea plaque on the teeth. Good foams. In order to brush your teeth, very little of this means is needed. Jars will last for a long time. A small jar of 30g. The lid of the jar is sealed with a plastic strip, which should be removed. So it all came out all along and very quickly. I'm very happy with the powder. Cleans very well.
