You can customize your jewelery by changing the type of chain (in the case of a necklace, lengthening or shortening it), the type of hook in the case of earrings (for example you can request clips). You can change the colours, and if for example you see an earring but you want to have the same subject as a key ring, I can do it! Write me a message before purchasing to check if the modifications you need are available, I will try to help you in any way;)
