Vintage Necchi Sewing Machine Needles Slide Tin lot of 5 Polished Italy; +hand

Description

Lot of 5 Necchi/Elna metal green slide tins for sewing machine needles.  The top green part is metal/tim and it says "Super Polished".  The bottom part is a see through clear plastic and it says "Made in Italy"
Two tins say  3 needles 15x1-11 they each have 1 needle in them.
There are 2 tins that say 25 needles 15 x 1 -16.  One is empty and 1 has 2 needles in it
The fourth tin says 25 needles 15 x 1 - 14.  This one has 1 needle in it.
These were found in a bunch of old sewing supplies  I have no idea if the needles are new or if they had been used.  Or even if they are the correct size needle as indicated on the case.  The points do feel sharp.  Even if the needles are not useable, the tins are unique and a wonderful advertising piece.  SELLING AS IS.
Also included in this sale is a Lot of 6 packages of hand sewing needles in paper packages with advertising for Prudential Insurance on the front.  Also says "Made In Germany" on the front.
These needles are from old stock but they appear to be new.
Four of the packages are full with 5 needles in them and the other 2 packages have 3 and 4 needles in them.
Thanks for looking
