Glide strips for wet shave razors in which the glide strips comprise a mixture of polyurethane and polyvinylpyrrolidone in a ratio of less than 3:1. Preferably, the ratio of PVP/PUR is in the range of 3.0 -1.0:1. Most preferably, the ratio of PVP/PUR is in the range of 2.5 - 1.5:1. Glide strips having a ratio within this range provide the benefit of allowing an additive, such as aloe or vitamin E acetate, to be incorporated within the strip in a manner so that it will be capable of depositing the material from the strip on the user's skin during usage. This will provide the benefit to the user of applying a material directly to the skin to enhance the shaving experience. A further embodiment provides a glide strip having a PVP/PUR blend of a certain color and ratio, which ratio will allow the PVP/PUR blend to erode as the razor is used. Upon the erosion of the PVP/PUR blend, the underlying material, of a different color than the PVP/PUR, will be exposed and provide an indication to the user that the razor should be replaced. 11
