Flexi Black Design L Leash 5m The Flexi Black Design S Leash 5m retractable leash is available in various colors and sizes. The leash is black, extends out, and has a silver carabiner hook attached. It allows for a lot of freedom of movement through the simple extension and retraction of the strap. The longer the leash, the more freedom you give your four-legged friend. At the same time, you always maintain control over your beloved pet. The short-stroke brake system ensures that you can rein in your dog at the push of a button. The different sizes of the Flexi leashes also mean that the handles vary in size. The larger the leash, the larger and more comfortable the handle. A rotary wheel on the handle allows the lower part to be adjusted to your hand size. The Flexi leashes also differ in pulling force and length. Size differences: S is 5 meters long and recommended for dogs up to 15 kg, M is 5 meters long and recommended for dogs up to 25 kg, L is 5 meters long and recommended for dogs up to 50 kg.
