All of our chain Necklaces and Keychains are made of Brass and are coated with a mixture of materials we are unfortunately unable to identify the exact composition of.
If you are prone to experiencing allergic reactions to worn materials, we suggest considering an item made with string (our Bracelets), as an alternative to an item containing a chain.
If you already purchased one of our items and you are experiencing an allergic reaction to it, we recommend to stop wearing the product and email us at serve@myintent.org so we may replace it with a different type of item of equal or lesser value.
