The phosphor leash is made of a strap with a special surface treatment, which is water-resistant and at the same time is very soft and pleasant to the hand. What is unique about it is that it is charged for night walks by wearing it daily. A little advice: Before the walk in the evening and calmly even during the walk, just illuminate the leash with a mobile light and the leash shines beautifully again. It shines for up to 45 minutes per lighting. The leashes are suitable for medium and large breeds.
