If, like me, is beginner waxing with wax cartridges, one wonders how much can stick the wax. After the first attempt, I had the odd bruise on her legs. In the second and third time I have been in practice and had drawn me no "injury" more. I am now very happy with the wax and it can only recommend. Practice creates masters.
The only downside: The wax is not soluble in water, you have to wax residues only with non-woven strips and then remove with oil and still not get mostly all gone.
One cartridge is enough for me for 1 max. 2 times legs (thighs and calves).
