The curtain looks like a wave-ball chain curtain, but it uses cloth tape to lock a distance instead of a ball chain. The cloth tape is solid and stitched with the curtain to set the curtain shape to be tidier than the ball chain. It is best for the house in the luxurious and modern style. Although this type of curtain is costly due to the expensive rod and equipment, it is popular broadly. However, the beautiful shape wins the flavor of the customer.
