What media can these brushes handle?

The nylon hair is listed for watercolor, oil and acrylic painting. Synthetic bristles tolerate water well and clean up easily, though they hold less oil paint than natural bristle.

How many sizes are included?

The set covers ten sizes, from broad brushes for washes to smaller ones for detail. That spread is what makes it useful for mixed classes and projects.

Are these good for professional artists?

They are labeled professional grade, but bulk nylon brushes are best treated as workhorses. Artists wanting precise tips and long life usually keep a few premium brushes for finishing work.

Synthetic brushes in large packs can lose a few hairs, especially early on. Rinse them before first use and wash with mild soap to reduce shedding.

How should I clean them?

Wash with lukewarm water and mild soap, reshape the tip, and dry bristles pointing up. For oil paint, use appropriate solvent first so residue does not harden in the ferrule.
