Extra large lever backs with flat eyelet
Jewellery ear lever backs are delicate earring fastenings that combine secure hold with an elegant look thanks to their folding mechanism. They consist of a movable hook that is inserted through the ear and then closed, ensuring that the pendant remains securely in place.
Their discreet shape allows the jewellery element to take centre stage and makes them particularly suitable for drop pendants, pearls or fine gemstone settings.
