Made in Japan by a small business and jewelry designer & extremely limited in quantities. The adjustable 360 ring can be worth in any configuration, giving it multiple styles and looks to choose from. The band is also opened and adjustable, allowing the ring to be swapped onto different fingers easily with a secure fit.
It is not recommended to adjust the size by more than 1 ring size often or there is a potential risk for the silver band to snap. Moving it between similar finger sizes will not compromise the strength of band. The distressed effect can be polished away with mineral fused metal polish cloth. Only use water, soap & microfiber/polish cloth to maintain the effect.
