Synthetic bristles are man-made fibers used in various brushes, including those for painting, makeup, and cleaning. These bristles are often made from materials like nylon or polyester, which can mimic the texture and performance of natural bristles, such as those from animal hair. One of the main advantages of synthetic bristles is their durability and ease of maintenance. They are typically resistant to water and chemicals, making them suitable for use with different mediums, including watercolor paints and oil paints. Additionally, synthetic bristles are often more affordable and suitable for individuals with allergies to animal products.
