Crystallized Titanium Square Bar Earrings Hypoallergenic

<How to Order> Please select your desired color from the options. <About the Design> These earrings are made from crystallized titanium — titanium cast to grow large crystals — cut into a square bar shape. The coarse crystal structure creates a uniquely sparkling surface pattern. When anodized coloring is applied, the pattern becomes even more vivid, achieving a texture impossible with ordinary titanium. The hooks and all other parts are also made from titanium with matching color. The all-titanium construction makes them incredibly lightweight — you may forget you're wearing them. <About the Colors> Using a technique called anodic oxidation, we control the thickness of the oxide film to produce a wide range of colors. Rather than dyeing the titanium itself, the colors are created by light interference through the oxide film — this is known as structural color. <Lead Time> Made to order. Please allow approximately 15 business days (excluding weekends and holidays) from the time of your order. Additional time may be required depending on current order volume. <Care Instructions> Titanium is highly resistant to discoloration, so no special daily care is required. If skin oils or dirt cause the color to appear different, gently wipe with a soft cloth. Avoid polishing cloths or abrasive materials, as they may wear away the color. <Precautions> Titanium is unlikely to cause metal allergies, but please discontinue use if you experience any skin irritation. The oxide film is very thin — color may chip if the piece strikes or rubs against hard surfaces. <Product Dimensions> Charm: 2.5mm × 2mm × 25mm (titanium) Hook thickness: 0.8mm (titanium)
