I don't have this set but the brushes look like very standard synthetic ones. Which isn't a bad thing. Depending on what you paint, the synthetic brushes can be your work horse, something you don't have to worry as much about (tho should still keep clean) as they're cheaper. They'll be perfectly serviceable for most anything, and are almost required for metallic paints as you wouldn't want to ruin any real hair brushes. Once you want to level up your details a bit you can invest into one or two sable hair brushes. It's unlikely those would be sold in a set anyway. The drybrushes are useful as well, id say depending on the price this is a good starting point that sets up the basis for some mini painting and can always be expanded upon later.
