[Thank you very much for viewing this product from among the many items on sale. My name is Panda Kottanantekotta-chan. Thank you. [Product Description] This product is a cube Kihei 6-sided finish chain with a genuine 24kGF finish. [Necklace] *Color: 24k Gold *Material: 24k Gold Filled *Width: 10mm *Chain Length: 60cm K24GF stands for Gold Filled, which means a thin gold layer. When choosing gold accessories, you will almost always see the notations "GP (Gold Plated)" and "GF (Gold Filled)". Although the names are similar, the amount of gold used is different. Gold plated GP is gold plating, which means it is thinly coated with gold. In contrast, ❈Gold Filled GF is not made entirely of 24k gold, but rather a thin film of 24k gold is applied to another material (such as titanium). It is similar to plating, but it is less likely to peel off. The thickness of the gold is said to be about 100 times that of gold plated GP. Gold plated (24kGP) may rub off and the gold may peel off due to friction as you use it, but this product, gold filled (24kGF), is made of a thick gold film, so the underlying metal is unlikely to be visible. Those with allergies can use it with peace of mind. It will not rust, but please wipe it lightly after wearing it for self-maintenance. For safety, please remove it when bathing in hot springs.
