I'm not quite sure what these brushes are for as on the packet which was not opened but returned it said suitable for watercolour, acrylics, and oil. You cannot use a watercolour brush to apply oil or acrylic paint. The brushes are more than soft. They have no substance to them. I ordered them hoping that they would be better than the last sable brushes I bought from these people but they are worse because they are saying that these brushes can be used for all types of painting which is just not true!! There are special brushes for different mediums.
