This golden chain bracelet has a number of small metal objects hanging from it like charms.

A wand bracelet can store up to four items, which appear as charms along the bracelet. You can grab one of the charms from the bracelet as a swift (manipulation) action, causing it to appear in your hand.
If you have an item in hand, you can use a move (manipulation) action to store the item in the bracelet or to switch a held item for a stored item by touching the item to the charm representing the stored item. Storing an item causes it to shrink down and appear as a charm hanging from the bracelet. Any item stored can weigh no more than 3 pounds and must be able to be held in one hand, such as a wand or a light weapon. Only the wearer of the bracelet is able to retrieve or store items.

Lore: The name wand bracelet describes the most common use of this item. Originally designed to hold small keepsakes as charms, and crafted to be appropriate for formal gatherings, wand bracelets have found popularity among artificers (ECS 29) who favor spell trigger devices (Knowledge [history] DC 15).
These bracelets are also sometimes known as assassins’ charms, because small weapons can easily be concealed within them (Knowledge [history] DC 20).
