Thank you for viewing. Used a few times after purchase. 【Regarding Material and Quality】 This is not a cheap plating with only the surface being 18K gold, but rather the base metal is 18K gold, so there is no risk of it peeling off. Of course, there is no worry of discoloration or fading. This product can be used in a beautiful condition for a long time. Also, please rest assured that the "K18" hallmark, which is proof of genuine 18K gold, is also engraved. 【Regarding Allergies】 18K gold is a material that is unlikely to cause allergies, so those with allergies can wear it with peace of mind (individual differences apply). 【Regarding Design】 The design is a simple Kihei chain, so it is an item that can be used by both men and women. It is a product that is sure to be appreciated as a gift and is worth more than the price. Also, because of its simple design, it is easy to match with any top. Of course, you can combine it with your favorite top, or you can wear the chain alone without a top and still look stylish. 《Length》 50cm (Adjustable to 45cm with an adjuster ring) 《Width》 1.65mm 《Weight》 Approximately 2g 《Specifications》 Made in Japan K18 (K18 hallmark) 《Difference between K18 and 18K》 K18 is made in Japan, 18K is made overseas 《Accessories》 Quality assurance certificate ※The case in the image is not included.
