Glass - All of our glass retainers are hand-crafted by highly skilled glass artisans, in small production batches. Only use high quality soda-lime and borosilicate glass for our raw materials.

Silicone - The heart retainer. By pinching both sides of the "heart" together it collapses, creating an extended reach for an easier insertion. Once the retainer is inserted the "heart" will open to create a flare ,holding the jewelry in place.
