Korean blinds, also known as combi blinds or zebra blinds. They are made up of two layers of horizontally striped fabric that alternate between sheer and solid panels. The sheer panels allow for filtered natural light to enter the room, while the solid panels provide privacy and light control.

By adjusting the position of the solid and sheer panels, you can let in varying amounts of light and achieve the desired level of privacy. They also provide a modern and stylish look to a room, and can easily fit into different types of windows.
