Most gold plated/ silver fashion jewelry may tarnish over time due to oxidation and residues/particles left over by some chemical liquid such as perfumes or sweat.
You may use this PE Film anti-oxidation jewelry storage film to store your favourite jewelry to make them last longer. The box comes with a stand.
Size: 9CM x 9CM or 7CM x 7CM
Tips: Just like silver, you may also try to reduce the tarnish (the darken color) on your gold plated jewelry by cleaning with jewelry cloth. This method may not be perfect shine, but at least to reduce the dark colors.
