This ear plug jewelry is designed to be inserted into a pierced ear lobe and used to stretch the piercing in the ear lobe. The jewelry contains a coin-cell battery that lights up a decorative pattern. The firm has received three reports of burn injuries to consumers because of leaking battery acid. Consumers should immediately stop wearing the recalled ear plug jewelry and contact SalesOne for a full refund or replacement ear plug that does not contain a battery and does not light up.
