Roller blinds are window coverings made of a single piece of fabric that can be rolled up or down using a cord mechanism. These blinds are designed to fit neatly at the top of a window frame and can be easily adjusted to control the amount of light and privacy in a room. The fabric is typically mounted on a tube, and the blinds can be operated by pulling a cord or using a spring-loaded mechanism.

Roller blinds come in a variety of materials, colors, and patterns, allowing for customization to match the decor of any space. They are popular for their simplicity, versatility, and ability to provide a clean and uncluttered look to windows. Roller blinds are commonly used in homes, offices, and commercial settings due to their practicality and ease of use.
