Silver plated bead brass chain hook earrings. Material: brass; silver plated. Earring length: 11.8cm (hook included). Chain width: 6.0mm. Brass oxidises easily than other precious metals and electroplating helps to reduce the speed of metal oxidisation, also gives it an alternative look. To keep the good condition, clean with neutral detergent or water (use soft brush if necessary) after wearing, wipe dry and leave in the air for about two minutes (vapour off) and seal in a zipper bag.
