Lucite or PTFE (Bioplast) with silicone o-ring N/A Rook, lobes, daith, snug, anti-tragus, tongue web, septum, helix, forward helix, conch, eyebrow, nipple, bridge, vertical labret, vertical lip, vertical philtrum, navel, and more! You can wear a curved retainer in surface piercings to hide the piercing and/or to prevent your piercing from closing during medical proceedures. The retainer is clear to keep it hidden, and unobstructive for whatever your piercing needs! PTFE (also called Bio-Plast) is a soft, flexible and biocompatible material. Lucite is a high-grade acrylic. Lucite is ideal for body jewelry because it doesn't leech chemicals into your skin. This is a risk with other, cheaper plastics. Both of these options are completely hypoallergenic! Both are ideal for hiding your piercings at work and events or especially for medical procedures (X-Rays, surgery, etc). The posts are held in place with silicone o-rings to ensure a secure, but accessable fit. For these reasons, this piece is a favourite for almost any piercing, and can be placed in the following examples: rook, lobes, daith, snug, anti-tragus, tongue web, septum, helix, forward helix, conch, eyebrow, nipple, bridge, vertical labret, vertical lip, vertical philtrum, navel, some intimate piercings and so many more than we can list!
