Metal barbell-shaped necklace with a 925 stamp. - Type: Necklace, 45cm - Material: Metal - Stamp: 925 - Design: Barbell This is for my son. I bought it as a souvenir when I traveled to England and France. I don't know how often it was used, but I think there is some natural dirt. I wiped it with a disinfectant wipe, but I didn't polish it. I thought it might not be good to make it too shiny. Since it's silver, I think it will become quite shiny if you polish it. The key chain that was placed with it will be included as a bonus. (30cm) Thank you for looking.
