Nano Coating for Metal is a sealant for impregnation which forms a transparent hydrophobic and oleophobic coating, protecting the surface from getting dirty, rusty, steamed, blurred or dimmed.
If you find your skin reacts to silver or brass, you may want to opt for this coating which will prolong the longevity of your item.
This is a service that can only be purchased with rings, earrings and pendants.
