【Size】 Length: 50CM, a comfortable length based on ergonomics, suitable for any style. 【Material】 Made of silicone and high-quality 316L stainless steel, with one germanium element on a silver stainless steel accent. 【Easy to Attach and Detach】 The clasp is a magnetic joint, so you can easily attach and detach it by twisting it left and right! ※ There are some scratches from use, but I don't think there is any noticeable damage when worn (in my opinion). Please judge the product based on the photos and understand that it is a used item before purchasing. We do not accept returns, refunds, or claims after purchase. Thank you.
