This is a wonderful pair of late 1950s / early 60s era gloves made in black satin.  The gloves have some expandability, so are probably made of a nylon rayon blend.

Label: Neyret.  Neyret was a French manufacturer based in Paris.

Size: Label reads size 7.  They have a length of 20” to the middle finger.

Condition:  Excellent - they look to have seen no use

This is a wonderful pair of vintage gloves, sophisticated accent for an evening dress.
