OK there are lots of feather cuffs out there but these are the first I have seen in solid copper. Very nicely done by Navajo artist Douglas Etsitty. They are a bit ajustable. One is 5 7/8" inside & opening 1 1/8" The other 6" inside & 1 1/2" opening. They fit quite a bit different. the smaller fits my 6 1/2' wrist a tad large. The other would probably fit a 7 1/2 to an 8" wrist. they are 3/4" wide.
