マリナーショートチェーンネックレス | 18金ゴールドプレート/プラチナプレート

The anti-tarnish claim is actually true—I've worn this in the gym and it still looks brand new with no discoloration. The 5mm chain width gives it just enough presence without feeling bulky against my skin.

The 45cm chain length hits perfectly at my collarbone, and the 5mm width feels substantial without being clunky. I’ve worn it daily for two weeks through workouts and showers, and the anti-tarnish stainless steel still looks brand new—no green skin or dulling anywhere.

I was worried about water damage, but this necklace has held up perfectly through showers and gym sessions without any tarnishing. The weight of the 22.4g chain feels substantial and luxurious for the price point.
