Features: 1. Made of high-quality metal and cotton rope, wear-resistant, not easy to break, reusable and durable. 2. Good exercise tool: Our spring bar is a muscle building tool for dogs. Dogs enjoy the pulling, swinging, and tugging action that spring bars provide, offering hours of interactive play. 3. Matters needing attention: The spring rod serves to reduce force and absorb shock; it is not an elastic rope. Toy cords are not indestructible and are not intended for chewing. 4. Easy to install: The spring bar can be hung on a tree, solid wood, or iron frame. Simple and convenient setup. 5. Suitable for dogs of all ages and breeds. A great gift for dogs. Notice: 1. Actual color may be slightly different from the image due to different monitor and light effects. 2. Please allow 1-3 cm deviation due to manual measurement.
