The listing, Blue Nile Ring Sizer - Brand New has ended.
Blue Nile ring sizer. Measures full and half sizes from size 3 all the way up to size 14! YES, SIZE 3-14!!! You can leave them in this hard plastic card or pop them out to put on a piece of string. The size is on each tab. The ones I have look slightly different than this one, it's the same color, but the outer plastic is shaped around each ring, for less waste. This will come directly from me, not from Blue Nile.
