LONE ONES Mating Flight Hook Black Leather Size: L Leather Thickness: Approximately 3mm Silver Hook (Longest): Approximately 4.7cm Length: Approximately 31.8cm (leather part) *Please refer to the images. *Image 8 shows a woman's wrist circumference of 15.3cm. *Likely size L. Measurements are approximate; please judge from the images. Materials: Silver 925, Leather It's too short to be a necklace, so it's more suitable as a bracelet. Never used. I think there's little oxidation (in my opinion). There is no guarantee or storage bag, but it is definitely authentic. I have stored it at home for about 10 years. (It's in good condition, but it's a used item.) Returns are not accepted to prevent switching. Used item, stored at home. Thank you for your understanding.
