pia+michio: Handmade products created by a Hawaiian artist. This collar, approximately 75cm, is spacious enough for large dogs. It features colorful stripes and is stylish, making it a unique item not available in Japan. I had it made in Hawaii a few years ago, but I'm selling it now because I no longer use it. I've used it a few times, but it was mostly kept at home because it got buried in my dog's long fur. I'm also selling the leash, so you might consider purchasing them as a set. - Color: Green and colorful decorations - Material: Rope - Design: Colorful stripes and hardware Thank you for looking. Please note that the size measurements are approximate, as they were taken by hand.
