MATERIALS WE USE JEWELRY CARE FLAT BACK EARRINGS

MATERIAL WE USE AND WHY

The answer is simple - Cords Club was designed for people with material sensitivity and/or allergies so we only use the best materials so that you can wear and enjoy your jewelry.

  • Implant Grade Titanium
    We use implant grade titanium because it’s super lightweight, hypoallergenic, and perfect for sensitive ears. It’s a durable metal that resists tarnish and keeps your ears comfy all day, every day.
  • Stainless Steel
    Our stainless steel components are strong, corrosion-resistant, and low-maintenance. This means your earrings stay shiny and sturdy even with everyday wear.
  • 18k Gold PVD Plating
    We add 18k gold plating for a rich, luxurious look that lasts. Our high-quality PVD plating resists fading and gives your earrings that beautiful golden look.
  • Phthalate-Free Enamel
    For our colorful Cutie Club designs, we use phthalate-free enamel to create vibrant, safe, and long-lasting colors.

MATERIALS WE DON'T USE AND WHY

  • Nickel
    Nickel is one of the most common causes of allergic reactions in earrings. We don’t use it because your ears deserve better than redness, itching, and irritation.
  • Phthalate-based enamels
    Many cheap enamels contain phthalates, which can be harsh on skin. We say no to that and use only phthalate-free enamel.
  • Low-cost base metals (like brass, copper, or mystery alloys)
    These metals may be cheap and affordable, but they oxidize fast and can leave green marks. We guarantee our pieces will never turn your skin green.

SAY GOODBYE TO "EAR"-RITATION

Itchy ears? Redness? A piercing that just won’t heal for ages? These are often signs of a metal allergy or sensitivity.

At Cords Club, we only use safe, hypoallergenic materials that keep ears happy. That means no mystery metals, no irritation, and no sacrificing style for comfort.

Our earrings are designed to look amazing and feel comfortable. If you’ve been struggling with irritation, itchiness, or discomfort, it’s time to upgrade your earrings.

If you decide to try our jewelry and your ears aren’t 100% obsessed, don’t worry! We’ll help with a quick and easy return.
