Vintage Clip On Earrings Blue Shell? Dangle - Glue to Rear

Description

These earrings measure just under 1.25". Really unusual and not uniform shape. Because of this the top hangs differently on both. Rear of one has some pad residue or glue I am not sure but it is hard and can be felt when on the ear - may need an after market cushion adding. Preowned vintage earrings, sold as shown - I am unsure of material type(s) because of this. Pictures show different angles for you to review - while I attempt to note any defects, some tarnish/signs of wear may be visible that are not otherwise stated. Earrings are tested and photographed on a thin/smooth earring stand (not included) to show that the clips are in working order.
