Ken Goldman's Ring Me Up is a unique ring that helps you keep track of all your receipts, allowing you to keep them literally on hand at all times.
Goldman uses jewelry as a vehicle for social commentary but what makes his pieces really unique is that they are functional and reflect a great sense of humor.
Implications - The ring has a long piece of metal that you can pierce your receipts through. There is a pearl placed on top of the metal bar so that the receipts can't fall off the ring. You can wear the ring as an interesting style statement or keep it on your dresser with all your receipts in check.
