The puppy collars are made of high-density nylon, offering flexibility, lightweight comfort, and a sleek appearance. The smooth, soft nylon material helps prevent irritation to your pet's fur and skin, allowing them the freedom to move and play comfortably. Available in multiple colors, these collars make it easy to distinguish between multiple pets. Designed to fit both puppies and cats, please measure your pet's neck circumference before purchasing to ensure a proper fit. The collar features a safety buckle that releases under pressure if your pet becomes entangled, helping to prevent injury. The buckle is designed with appropriate resistance to avoid accidental release, yet will open when necessary under sufficient force. It is not easily triggered by scratching or normal movement. Each collar comes with 12 bone-shaped identification tags that match the collar color, allowing for personalized labeling. You may use the included label stickers or write directly on the tags with a marker. These durable and stylish tags provide a practical and attractive way to identify your pet.
