All the products from PMW are manufactured with Korean technology, also certificated by CE, FDA, ISO13485 and ISO9001. Swabs are produced by using water-based adhesive, not oil-based one.

It is designed to collect samples from the enterance of nose or throat easily, with no deep insertion to the nasopharyngeal or oropharyngeal areas.
