PearlMax: This is a brand that sells women's razors. They offer a "PearlMax Comfort 3" women's razor, which features three blades. The name "Pearl" is a direct part of the brand.
Schick Quattro: One listing mentions a "Schick Quattro For Women Razor Enriched With Papaya & Pearl." In this case, "Pearl" is an ingredient in a moisturizing strip, not part of the brand name itself. The Schick Quattro typically features four blades, but this could be a special edition or a different model.
Generic"Pearl" Razors: Some retailers might simply use the word "Pearl" in their product descriptions to signify a feature, such as a moisturizing strip, even if the brand isn't PearlMax.
