Kula ring
Kula valuables are usually passed on to their trade partners after a certain amount of time, therefore the valuables are always moving around the Kula Ring. The person who originally owned the valuable has full ownership and rights over the item, so he can keep it, sell it or even break it. Every person who therefore receives the item, does not fully own it, as there is always a true owner. This creates a sense of responsibility over how the object is handled by other traders toward the original owner. However, the original owner is sometimes unknown, lost in the Kula Ring.
