Probably in one or more occasions you have been in an art shop staring at the paintbrush stand, without knowing which paintbrush to choose due to the immense variety you have found. Shape, type of bristles, thickness, length, etc. It is somewhat complicated if you do not know the materials or are not clear about the most appropriate use for each of them.
The paintbrushes can be made of natural or synthetic bristles. Which one is better, natural or synthetic bristles? Some of the natural bristles are softer than the synthetic bristles, which is why some artists prefer to use this type of brush in their artworks.
However, synthetic bristles are more versatile, require less care, and are more resistant to damage from solvents. Natural bristle brushes are made from the hair of wild animals such as weasels, squirrels, horses, ponys, pigs, etc. Synthetic bristles filaments are made from polyester, nylon, or taklon fibers. There are also bristles coming from plants like the Ixle that comes from the Agave plant.
