We mainly work with stainless steel which is tarnish proof and good for most sensitive ears. All of our chains and earrings are stainless steel. Some charms may not be stainless steel. We also use polymer clay which is a strong and durable material. Although strong it can be broken with improper care. Store your jewellery in a safe place. Avoid showering or swimming while wearing your jewellery. Keep away from harsh chemicals or perfumes to preserve the colours. If you need to clean your jewellery, wiping it with a damp cloth and patting it dry will do the trick.
