I realized I purchased the wrong size. Since returns are not accepted, I am selling this item. I checked the size from the bag, so it has not been opened. Thank you. The product description is below. Product Description ▼Color Blue ▼Material Polyester, Nylon ▼Size Size 1 Weight: 1-3kg, Chest: 23-33cm ・Harness designed for small dogs. Attach the leash to the ring at the end of the strap. Adjustable straps maintain a relaxed state, but when the dog pulls or the owner pulls the leash, the harness tightens and fits closely to the body. ・Recommended for puppies and training. The soft and comfortable soft mesh fabric is lightweight and breathable, reducing the burden. Reflective threads that reflect light are woven in, making it ideal for nighttime walks. The Liberta series can also be used for cats. Thank you for viewing.
