Bachelorette party activity in Stockholm – silver jewelry in silver

Are you looking for a memorable and fun activity for a bachelorette party in Stockholm? The activity can also be done at birthdays, girls' get-togethers, etc.
Then we can recommend this bachelorette party activity where the bride gets to punch her own name jewelry/necklace in silver. Punching in this context means hammering/writing letters and numbers on a silver rod (pendant/necklace)… e.g. her name, future husband's name, children's names, wedding date. The silver rod has four sides/surfaces to punch on and the pendant can rotate when it is then hung on the silver chain.
