Package of 72 Vintage Japanese 24" Brown shoe Laces

From the 1940s/50s these big packages of shoelaces are Scull Brand.
Made in Japan, 24" long, cotton with metal ends.
Half a gross - thats 72 - in each package.
Because who doesn't need 72 brown shoelaces ?
I've got 10 unopened packages and 1 open without the label (but still tied in a bundle)
