● Effortless No-Drill Installation (Rental-Friendly): Upgrade your windows without the power tools! Our tool-free "Inside Mount" system is the perfect solution for renters and DIYers, requiring zero drilling and leaving no permanent damage. Designed for window frames with a minimum depth of 6cm, the innovative tension mechanism provides a flexible width adjustment of (x-0.5) to (x+1.5) cm for a rock-solid, secure fit.

● Premium Light-Filtering & Privacy Protection: Crafted from high-quality 100% Polyester, our Light Gray semi-blackout fabric strikes the perfect balance between natural light and privacy. It effectively diffuses harsh sunlight to reduce glare and protect your furniture from UV rays while creating a soft, inviting atmosphere in your living room, home office, or bedroom.

● Precision Fit for Outward-Opening Windows: Specifically engineered for windows that open outward, our slim-profile hardware is designed to clear window handles for a smooth, snag-free operation. To ensure a perfect fit, simply provide the minimum inner width (measured at the top, middle, and bottom). We manufacture to your exact inner dimensions with no deductions, providing seamless edge-to-edge coverage.

● Heavy-Duty 28mm Reinforced Aluminum Hardware: Quality you can trust. Each shade features a thickened 28mm aluminum alloy top rail to prevent sagging and ensure long-term stability for custom widths up to 65 inches. The high-precision manual bead chain (default on the right) ensures an effortless, smooth glide for reliable daily light control.

● Modern Minimalist Aesthetic & Easy Maintenance: Enhance your interior with our sophisticated Light Gray finish, offering a clean, contemporary look that complements any decor. These indoor roller blinds are not only stylish but also highly practical—the durable polyester fabric is moisture-resistant and incredibly easy to clean with just a damp cloth.
