FUNCTION: Blackout curtains can block 70-80% of the light (the darker color works better), and can also reduce noise and keep heat down in summers or keep cold out in winters to achieve smart energy saving and provide privacy.
FINE DETAIL: Each curtain has 8 HOLES and the inside diameter of the GROMMET holes is 1.6 inches. And Every edge of the curtain is well sewn.
KINDLY REMIND: Due to the production process, the curtains may appear plush silver reflective under different light intensities and angles, and the color may also be different in different lights or on different screens. Please allow 1~2cm deviation due to hand cutting and sewing. If wrinkled, use a low-temperature steam iron to iron the back and front of the curtain. Machine washable in cold water and tumble dryable
