The Beeztees Safety Gear Parinca Premium Collar is a comfortable dog collar to wear. The inside is lined with neoprene, which is breathable and weatherproof. Neoprene is water-resistant and dries quickly. In addition to being used as a regular dog collar, it also serves as a luminous collar for your dog, ensuring that your pet is visible even in the dark. The LED lighting (with battery) is integrated into the waterproof snap closure and can be set to three different modes: slow flash, flash, and fast flash. It lights up in red, green, and blue. The collar is equipped with load relief to reduce pressure on your dog's throat and prevent material tears. The Parinca dog collar pairs perfectly with the matching Safety Gear Parinca dog leash. - Neoprene lined - Includes LED lighting - Includes batteries (CR1225) - Reflective - Load relief.
