Jewelry featuring a flattened rear surface, typically crafted from a precious metal, provides a secure and comfortable fit against the skin. These items, often made with hypoallergenic materials, are designed to minimize irritation and are commonly used in earlobe piercings. Examples include studs, barbells, and labrets that incorporate a level plane intended for direct contact with the skin behind the ear.
Their increasing popularity stems from enhanced comfort and reduced risk of the backing digging into the skin, particularly during sleep or when wearing hats or helmets. This design promotes better hygiene by allowing for easier cleaning and reducing the accumulation of debris. Historically, similar designs have been utilized in various forms of body adornment across cultures, evolving with advancements in metallurgy and piercing techniques to prioritize wearer well-being.
