Thank you for viewing! I purchased these at a department store, but they are almost unused. Retail price: 9800 yen x 2 The pearl necklace bead sizes are 5mm and 3.4mm. The length of both is 40cm-45cm (adjustable). The purchase dates are indicated, 2023 and 2024. You can purchase them together or separately. If you only purchase one, I cannot include the case. ^^; I hope you can use them for various occasions such as weddings, fashion, and formal events. Thank you. Thank you.
