This is a custom-made choker and bracelet set purchased at a crystal bead shop in Hanoi, Vietnam during a visit. They were made to order as a souvenir for adults, so they are made to fit snugly. The choker is 30cm + 5cm, and the bracelet is 15cm. They are perfect for adults, and the sparkling design is so lovely that children will also love them. Thank you for looking.
