Kidney Transplant Gift! Have a lot of keys? This is the super sized kidney key ring in my collection, all sterling silver, oval shaped, flat ring rather than rounded. Size of the ring is about 35mm x 27mm, which is about 1-3/8" x 5-1/16." The kidney on this ring has a brushed finish so won't show scuffs from being scratched by metal keys as readily as a highly polished finish. Size of the kidney itself is 20mm x 10mm X 6mm.
Total length of the finished keyring is 2.5."
