Thank you for viewing. These are blackout, waterproof curtains. The size is approximate, as I measured them myself: 100cm x 230cm, two panels. The back is coated with acrylic resin. ◉ Acrylic resin coating on the back of curtains is a process that involves applying acrylic resin to the back of the fabric to block light (complete blackout), and enhance heat retention, insulation, and soundproofing effects. Even light-colored curtains will appear almost black, providing privacy protection. They are characterized by a slightly stiff texture and are popular with those who prioritize functionality. ◉ Benefits: Complete blackout (almost 100%): Blocks sunlight, ideal for bedrooms and rooms where you want to completely block out light. Heat retention and insulation: The coating layer creates an air layer, enhancing heating and cooling efficiency. Soundproofing effect: Can also reduce external noise. Privacy protection: Makes it difficult for the silhouette of the interior to be seen from the outside. Protection of the front fabric: Prevents fading and deterioration from direct sunlight, making the curtains last longer. These were stored at my parents' house. I opened them and tried to fit them, but they didn't work, so they've been left unused. Because the material is sturdy, they weren't folded neatly during storage (at my parents' house), so they have some wrinkles. However, I washed them with water, dried them in the shade, and wiped them for the listing. The curtain hooks are also included. In my opinion, they are quite thick and have some weight. They have good waterproof and blackout properties. They are a large size, but I hope someone can use them. Thank you very much. Please note that I am also listing these on other sites, so they may sell out.
