It looks like a wave-ball chain curtain with the curtain itself and the ball chain that locks the wave distance. However, it uses the décor rod instead of the aluminum rod because this type of curtain highlights the beautiful rod. The customer can choose any preferred colors. The only limitation is only three rod holders are allowed at one installation position. So, it might not be suitable for the wide window or doors, such as more than 3.8 meters as the rod might bend. It is recommended to get our suggestion after the site visit.
