Tre Ponti harness. Flat, for small dogs, about 37 cm. I remember purchasing size 1.5, likely for a dog weighing 3-4 kg with a chest circumference of 28-32 cm. [Country of Origin] Italy Easy to put on and take off, just fasten the plastic buckle on the back. I tried it on indoors after purchase, but it didn't suit my dog's fur color, so I'm selling it. The regular price is about 4500 yen, designed for small dogs. The back buckle is easy to attach and detach, and the simple design doesn't hinder movement during daily walks, dog runs, agility, and other exercises. The material is lightweight, durable, non-allergenic, water-resistant, quick-drying, and easy to care for.
