I have several of these collars on my etsy.com for sale. I have more sizes than listed, so message me if you are looking for a certain size. I put these up and decided that I will donate 15% of the selling of this item to charity. Charity as in various organizations for animals. I am a true animal lover and want to help them, so I made this "our" opportunity to help organizations that take the time to help pets in need.
