Immediate purchase OK. This is an authentic product. Safety design that detaches when strong force is applied. The neck circumference can be adjusted in 5 levels, and the wide shoulder guard firmly protects the shoulders from food spills. It can be rolled up compactly for convenient storage when going out. The deep pocket catches food spills. Easy to clean by simply washing when dirty. There is a hanging hole for thorough drying. Hmm. New, unused. I am selling it because I haven't had the chance to use it!
