Publication number: 20160106348Abstract: The present invention provides a personal hygiene item. In simple terms, one of the main features of the present invention is to provide a low-cost personal hygiene item capable of providing a multi-component detection function. The personal hygiene item of the present invention mainly comprises a first material layer and a second material layer. The first material layer is made of hydrophobic material, and the second material layer is disposed thereon. Also, the second material layer comprises a discolored portion.
