Thank you very much for viewing. I am still decluttering, having passed my 60th birthday! I was obsessed with these types of products for a while and collected them. This is a bracelet made by SEV. There are scratches on the silicone ring (see photo 3), and it shows signs of use. Recommended for those who just want to try out the function! Total length: 19cm I purchased this from an online store, but since there are many counterfeit products on the market, please purchase with your understanding. Also, as it shows signs of use, please refrain from purchasing if you are sensitive to such things. Returns are not accepted after shipping, so please understand.
