First of all my jewelry must be thought and then drawn, then the choice, with the utmost care, of the material and finally made. In fact, even if they seem delicate, thanks to the excellent materials I use are resistant enough that allows you to have a unique jewel forever. Metal parts in contact with water can change color slightly. I highly recommend avoiding contact with perfumes, oils, sunscreen, and not wetting. They must be kept in its packaging to avoid various scratches or stains in contact with other elements. Being a product made entirely by hand, for those who want to customize it or ask for more information contact me here crinnaxd@yahoo.it **** to be added the cost of shipping with registered international mail ( 14 euro)
