This container is full of keepsakes, greeting cards, ticket stubs, and other miscellanea of significant sentimental value.
No longer obtainable through a quest, Precious Keep-Sakes is nowadays considered as a rare item prized by collectors.
It used to be placed in the player's inventory in the last mission of the Borvo the Hutt questline, after killing a thug named Montrus. From there, it was possible to keep this item by not completing the delivery back to Borvo. Turning in the Precious Keep-Sakes with Borvo will get you another transfer item, the Tusken King's Rifle.
