Curtain slides are not smooth enough after a long time,you glue it across the curtain rod so that your curtains have a smooth,clean surface to slide across! The shower curtain always snaps on the shower curtain rod attachment point with glorified clear tape,attach it to the shower curtain rod and the shower curtain with the rope loop slides back and forth nicely. Curtain tape is made of high quality adhesive film,strong and durable,curtain puller tape can stick to almost any surface without hurting them. You will receive 2 rolls of clear curtain sliding tape 1.5 cm/0.59 in. wide and 3 m/118 in. long for your everyday needs. The curtain tape is easy to install You don't need to remove the curtains or remove the rod,clean the rod first,then start at one end of the rod and stick it to the entire length of the rod,gently press to make it fit to complete the installation.
