We've been conditioned to think that multi-blade razors are the only option, especially for women. Incumbents have trained women to feel that they're incapable of using a "real" razor, essentially wrapping them in plastic bubble wrap and soap, under the guise of innovation. Our customers have proven that this is bull. Second, multi-blades became the defacto choice because the patents on the machinery for single-blade razors expired, leaving room for competitors to enter the field. Plastic razors, with the help of marketing spend, were quickly the most prevalent option. Given that plastic takes 1000 years to decompose, imagine that the first plastic razors ever made in 1960 are actually still in our eco-system and billions more join them every year.
