The MoMA store is selling an innovative Magnetic Ring for $35. "This ring is made from three nickel-plated magnet arches which can be added or removed to fit a range of finger sizes. Four spacers of various shapes are also included to alter the ring's design and adjust its size."
Implications - You wouldn't have to worry about getting a ring stuck on your finger if you were wearing these Magnetic Rings. In fact, changing your ring would be as simple as clicking it on and off with ease. Then you would be free to change its design and size on the fly without any kind of hassle or frustration.
