Ultra-sheer 15 denier 66 gauge slinky plain knit Fully-Fashioned, non-stretch 100% nylon stockings. We have not opened a pack, so we are unable to ascertain the style of the heel stem, but we feel that it is reasonable to assume that these have a fine (narrow) Cuban heel (based on similar nylons by the same manufacturer). These wonderfully sheer classic vintage nylon stockings, made in the USA probably date from the 1950's. There is an imprint on one stocking-top in the pair, as can be seen in the scans and they are offered to you in the original cellophane packs, which are in remarkably fine condition.
