This acrylic labret retainer is flexible for extra comfort. The wearable length is 5/16" and the full length is 1/2". The acrylic labret retainer has a groove to hold the included o-ring. Available in both 14g and 16g.
This product is great. I'm able to wear it while playing volleyball and it doesn't move out of place or get noticed by the referees. Its also soft enough that I wouldn't lose a tooth if it were to get hit by a ball. That's always a plus.
I really like this retainer its very comfortable and is short enough to wear to work and you dont know its there unless you really look for it. And it doesnt effect my work effort since I dont even know its there! Very nice.
