I buy Payson's collars from If it wags. Payson is small and MUST have a martingale collar and she makes them in all sizes. All her of her designs come in regular flat style and martingale. Plus I think her collars are super cute, I usually don't like most collars I see. However I don't buy them off her website, she also sells her collars on Ebay for much cheaper than what she does on her website!
