NOVELTY - This utility new type provide a safe one set, comprising sleeve body set by polymer layer and graphite layer compose, graphene in a polymer layer, by two-dimensional graphene or graphene three-dimensional, one layer, two layer and three layer or multi layer are a. polymer layer by latex, polyurethane or one of a set or more of a body, a safety set in a can is SEBS polymer and graphene mixture is made by a single layer structure. This set can be safety barrier particle diameter less than a virus, more valid to prevent transmission of disease.
