Custom features in sex dolls—such as unique facial expressions, body shapes, or detailed anatomical features—are highly influenced by the base material used. Silicone is the superior choice for creating highly detailed and customizable features. Its malleability allows artisans to craft intricate details, from realistic facial features to textured skin patterns. Silicone can be easily sculpted and painted, enabling personalized touches that match specific preferences. Moreover, silicone can be modified post-production for repairs or customizations, making it ideal for those seeking a unique, tailored doll. Conversely, inflatable dolls, typically made from PVC or similar plastics, are manufactured through molding processes that limit customization options. These materials are less flexible and cannot be easily reworked after production, restricting the ability to add or adjust features. Therefore, if customization and detailed feature creation are priorities, silicone is undoubtedly the better material, offering versatility and the capacity for highly personalized designs.
