I'm selling this because it no longer fits my 5.5 kg toy poodle. It has been washed with laundry detergent and air-dried, so there should be almost no odor. Material: 70% wool, 30% nylon The green and blue wool with musical note patterns is cute. As cold days continue, how about protecting against the cold with the warmth of wool? Please check the condition in the images before considering a purchase.
