Roller blinds are a type of window covering made from a single piece of fabric that rolls up and down on a cylindrical tube. They are designed to block out light, provide privacy, and enhance the decor of a room. Available in various colors, patterns, and materials, roller blinds can be customized to fit different window sizes. These blinds operate using a simple mechanism, often involving a chain or a spring-loaded system. When pulled, the fabric rolls down to cover the window, and when released, it rolls back up. Roller blinds are popular for their ease of use and minimalistic design.
