Abstract

A multi-layered wiper for removing a product (e.g., a cosmetic product) from an applicator. The multi-layered wiper comprises a wiping body having a wiping face, an acute wiping tip, and vertical slits, formed of a first material, over-molded to a retention body, formed of another material harder than the first material. By virtue of having a multi-layered wiper comprising a wiping body, formed of a first material, over-molded to a retention body, formed of another material, harder than the first material, the multi-layered wiper is capable of providing exceptional installation characteristics, while simultaneously providing exceptional wiping characteristics.
