Do you love vintage boxes? This box still retains its original contents of Robinson Nylon Shoe Thread Bobbin - in black. According to the box - each bobbin contains 12 yards of thread - 1/2 gross (whatever that means). The box shows some soiling and wear - but is fairly mild. Graphics are blue (almost teal) and white coloring. Box measures approx. 3 1/4" x 4 1/8". I counted 40 bobbins inside. Thread is dusty and each bobbin measures just 5/8" across.
