This is a pair of matching mirror image lucite bangles. One is black, the other is white or pale cream. Both are domed with flat bottoms, so they can be worn stacked with the flat sides together, as shown, or any other way you like. They have an opening of 2 5/8" and the width is irregular. The widest point is 5/8" and the narrowest point is 3/8." Both are in excellent condition. They are not marked or signed.
