Lead: Approximately 120cm Harness (chest): Approximately 35-40cm I believe it's a size S. I used to use this, but it no longer fits, so I'm selling it. There are some minor scratches and fading. It has been washed. (This item is used.) Also, as I am an individual seller, there may be differences in the color of the images, oversight in the inspection, and errors in the measurements. Please understand this before purchasing. I will answer questions to the best of my ability, so feel free to ask.
