Gorilla Glass Labret Retainer

Hide your piercing with a clear glass labret retainer.  Ideally suited to ear lobe and cartilage piercings.  The clear silicone rubber o-ring maintains a secure fit when the retainer is worn.

Borosilicate glass is hypoallergenic and safe to wear in body piercings.   It is also safe to be sterilised and worn in healing piercings.  We particularly love this item for its suitability for wear during MRI procedures.  Removing jewellery for this procedure can risk the loss of a piercing.

Please note, this item is fragile and will break if forced or dropped.
