Set with findings that have an oxidation film treatment to keep your pierced ears clean. ◇ Are your pierced ears clean? ◇ Earrings are an important part of fashion, but people are surprisingly inattentive to their pierced ears. Small pierced holes are prone to bacterial growth due to sweat and dirt from the skin. Those bacteria can also cause unpleasant odors. Off-Time Earrings are specifically designed for pierced ears, with a special treatment (a photocatalytic antibacterial oxide film on the surface) that breaks down bacteria and dirt on 100% titanium. Simply wear them on your days off or before bed, and they will keep your pierced ears clean. ※ By "anodizing" the surface of pure titanium with electricity and chemicals, a stable, glass-like film "anodic oxide film (TiO2)" is created. This oxide film has three special effects. 1. When exposed to ultraviolet light (sunlight, fluorescent light), it uses that energy as a catalyst (a factor that causes a reaction) to decompose surrounding water, generating oxygen with antibacterial properties, and exhibiting high antibacterial and sterilizing power. 2. Because the oxide film is very stable, it does not ionize even when it comes into contact with the skin. Therefore, it does not cause metal allergies like other metals. 3. The titanium oxide generated on the surface of pure titanium has a hexagonal, transparent columnar shape. These crystals reflect visible light like a prism. Therefore, beautiful colors can be obtained by adjusting the thickness of the film in angstrom units. 【Specifications】 Frame: Made in Japan, pure titanium (oxidation film treatment) Shell Pearl: 10mm (white pink) Thank you for viewing.
