This set includes 15 shower curtain ring hooks made from durable iron-zinc alloy with a nickel-plated surface treatment, suitable for humid environments. Each hook features engineered spherical roller balls that reduce friction, allowing smooth and effortless movement along the shower rod. To install, open the clasp, loop the hook through the curtain or liner openings, then snap the clasp closed and slide onto the rod. Alternatively, stretch the open ring around a fixed curtain rod; the ring will return to its original shape. The hooks have an inner width of 35mm and a height of 70mm, providing a secure fit for various curtain sizes. Their silver tone finish offers a sleek appearance, making them practical and reusable for bathroom, bedroom, kitchen, or home curtain applications. These versatile hooks are designed for easy installation and long-lasting use in humid or everyday environments.
