This item is brand new. I am selling it because I ordered the wrong size. The chest area uses double-russell fabric, which is breathable and cushioned, reducing the burden on your dog. It's easy to put on with a one-touch buckle that doesn't require adjustment every time. 【Material】 Body: Cotton/Polyester, Tape: Polyester 【Suitable Size (Girth)】 35-55cm, Tape Width: 15mm 【Suitable Breeds】 Small dogs (up to 10kg)
