1【Size introduction】The listed size ( 33" W × 64" H ) is the window opening size for inside mount. The actual blind will measure slightly smaller ( 32 3/5" W × 64" H ) to allow space for mounting. For outside mount, add 2–6 inches to both the width and height of your window to ensure full coverage and better light control. 2【Honeycomb Structure】The standout feature of these blinds is their unique honeycomb structure. This design is not only aesthetically pleasing, but it also provides excellent insulation. The air layer within the honeycomb structure can prevent heat loss, thereby helping to maintain the indoor temperature. Additionally, the honeycomb structure can absorb sound, reducing noise and creating a quiet and comfortable living environment. 3【Aluminum Alloy Top and Bottom Rail Profiles】The top and bottom tracks of the curtains are made of aluminum alloy material, which is rust-proof, sturdy, and durable. 3【blackout fabric】Our blackout fabric is engineered for complete light blockage, providing total darkness and maximum privacy whenever needed. Ideal for bedrooms, nurseries, and media rooms, it effectively blocks sunlight and harmful UV rays—helping to regulate room temperature and reduce outside noise. Durable, stylish, and functional, this fabric creates the perfect environment for restful sleep and focused relaxation. 5【Safety Design】Our curtains use a no-pull system, without any cords, ensuring safety and reliability, and eliminating potential safety hazards.
