Made for us by a longtime New Mexico button artisan, this nickel silver shank button comes in either 5/8" or 3/4" in diameter. This is for the 5/8" size.  It has a bit of shine and a traditional morning star / sun rays design.  Its shank opening is a loop about 3mm. 

 Limited supply. This maker has now retired, so once these are gone, they're gone.
