Our BioThane Grooming Supplies have been called game changers by many professional groomers. They are made from official BioThane which is made in the USA. BioThane has a polyester webbing coated in rubber-like PVC. Even the narrowest option has a strength limit of 750 pounds so no worries about it breaking with use. It is waterproof and non-porous so it is very easy to clean and sanitize.
