♥Spring System: The blackout roller blind features a high-elasticity silent spring built into the top, requiring no fixation at the bottom. It can be freely extended and locked at any height with one hand, and gently pulled and released to automatically retract. You can freely adjust indoor lighting, privacy and ventilation according to your needs. ♥Premium Material: The sunshade roller blind is made of high-density polyester fabric that is eco-friendly, safe, healthy and odor-free. The thickened material effectively resists everyday wear, tearing and aging, ensuring durability and sturdiness. The surface is treated to be waterproof and oil resistant, making it easy to clean and maintain. ♥Comprehensive Protection: The thermal roller shade effectively blocks most direct sunlight and uvs, eliminates glare interference, protects your skin and furniture from damage.

The simple and convenient operation allows for easy, mark-free installation and removal.
