Yes! Earring backs come with all of our pierced earrings as they are all stud post style earrings that require backings to wear. We give 2 different pairs of earring backs for free with every purchase of pierced earrings, including: Traditional earring backings: These are the typical metal butterfly earring backing you would get with any pair of earrings, in matching metals to the earrings you purchased! Our comfier heart earring backings: These luxury backings are not just adorable, they're also more comfortable! Typically, people tend to find the squishy silicone of these more comfortable than metal pressing into the back of your ear. They are also better at supporting the earring, which can help prevent holes from stretching. This can also help those with stretched holes to achieve a more upright look to their earrings, as if their holes were not stretched! They're definitely worth a try and earring backs are easy to lose, so we thought we'd go the extra mile and give you the extra pair for free! Because you deserve it :) Both pairs of earring backs are hypoallergenic, water-proof, and tarnish-proof! Our heart backings are fully hypoallergenic as no metal touches the ear! The squishy part is silicone so they are latex-free. If you lose a backing, email us at shopatrenda@gmail.com and we can help set up a replacement purchase for you! We are working toward having extra backings of both types available as a bulk purchase through our website (since they get lost so easily!), but until then we will be handling replacement purchases through email. Thank you for your patience and stay tuned for that!
