12 Pack Curtain Rings: The plastic curtain hooks kit has 12 rings, enough for your replacement and daily use. When installing, you only need to hang them on the rods and rails to pull the curtains, and the lightness and flexibility make them more convenient to install and remove. C-Shaped Sliding Hook: Our curtain rod hooks feature an open C-ring for smooth sliding. They slide freely on shower rods and curtain rails without making much noise. The plastic material ensures that they will not rust in humid environments, so rust stains can rub off on curtains or shower curtains. Wide range of use: The shower curtain ring has a good pulling effect and can be used as a shower curtain hook and is widely used in bathtubs, bathrooms, dressing rooms, bedrooms, etc.
