Thank you for viewing. This is a dog seatbelt. It's adjustable in length and has a metal hook. It's the type that you secure to a harness with the hook. The green tape part is approximately 60cm at its longest. - Color: Green - Type: Seatbelt leash - Hardware: Metal hook - Adjustment: Adjustable length I'm selling it because it didn't quite fit my car and dog. It was only tried on once. Please refrain from purchasing if you are looking for a perfect product, are concerned about the details, or are overly sensitive. Thank you for your understanding regarding the above and that this is a used, personal item.
