Wear this set all together for a one-and-one-half inch band of shiny Bakelite on your arm. Or use these as spacers between your black and cream bangles. (See the ones I have just listed!) Or alternate with the set of five black spacers listed as 1414. (Discount if you buy both sets.)
There subtle differences in width and shade (some have probably been worn more than others) but there is no doubt that these were originally sold together. They are about 1/4 inch by 1/4 inch, and the openings are all 2 1/2 inches across. I see a small area of wear along the edge of two bangles, but the rest are in excellent condition.
