I chose these color, plastic hook sets in two colors (for two bathrooms) to replace the metal, roller style hooks that had unfortunately pulled threads, caused runs and damage to a brand new towel after it was hung over the top of the shower curtain rod.
    I like how the colors I chose coordinate with each of the bathroom shower curtains and I'm confident these plastic hooks will not rust. I made sure to position the smoothest edge of the plastic hooks on the top of the shower curtain rod. I don't expect any more problems with towel damage with this style/material rings.
