The Last Unicorn jewellery is made from silver and gold plated metals. 
If you have sensitive skin, we would recommend making sure you can wear these kinds of materials before purchasing your new items.
Due to the nature of the materials we use, some tarnishing may occur over time. To prevent our jewellery from discolouring and wearing down, we do not recommend having your jewellery come into any contact with water, perfume or salt water. Some of our items (will state on the product page) are fine to swim and shower in.
