Classic Italian slinky plain knit sheer stretch seamfree stocking, featuring a mousse (stretchy) top for additional comfort. The denier is not specified, but our estimation is that these are 15 denier all-nylon stockings, and feature a shadow (shaped) heel and shadow toe.
The pack refers to the contents as being 'Collants' (i.e. tights/pantyhose), but the contents are definitely stockings, NOT Collants.
