This listing is for ONE pair of the earrings.
Dimensions: 16 mm long
Material: plated brass

This earring only requires one standard ear piercing and is very easy to put in and it's shaped similarly to a bobby pin.
To put it on simply place it through your pierced hole like ordinary french wire earrings and then flip it to the side and slide it over your ear. Give them a gentle pinch to keep it in place.
