Our dog bandanas are made for party pups and disco dogs. Humans can wear these too and match! The black holographic fabric sparkles and reflects all the colors of the rainbow to ensure getting noticed at the dog park and out on walks. Classic tie-back bandana is crafted with a double ply fabric - holographic spandex on the front and a soft black stretch on the back. The ties have been designed to reduce bulk for easy knotting and a perfect fit for comfort. Stretch makes it easy to take on and off without having to retie each time.
