Important Fit Guide–Measure Before Ordering: Designed for inside or outside mount. For inside mount, window frame depth is required for proper installation. Shade width is made slightly smaller than the listed size to ensure smooth operation. Please measure window width & height carefully and refer to the size guide to avoid light gaps or fit issues. Blackout Fabric with Light Gap Awareness: Blackout honeycomb fabric effectively blocks light for sleeping, naps, and privacy. Like all cellular shades, small light gaps may appear at the sides or bottom due to window frames and mounting style. For maximum darkness, outside mount or wider coverage is recommended. Cordless & Child-Safe Lift System: Cordless spring-loaded mechanism allows the shade to stay at any position you stop, providing a clean look and enhanced safety for children and pets. Smooth, balanced lifting and lowering without tangled cords. Honeycomb Structure for Year-Round Comfort: The cellular(honeycomb) design traps air inside the cells, helping reduce heat loss in winter and heat gain in summer. Also helps block UV rays and outside light while maintaining indoor privacy. Easy Installation & Simple Cleaning: Includes mounting brackets, screws, and clear instructions for quick installation. Durable non-woven fabric resists peeling and fading. Clean easily with a feather duster, soft cloth, or vacuum brush—no special care required.
