Seamless rings are a popular type of body jewelry commonly used for various piercings, such as septum, daith, helix, and lip piercings. These rings are designed with a small opening that allows for easy installation and removal, giving them a seamless appearance when worn. Made from high-quality materials like surgical steel, titanium, or gold, seamless rings are durable and hypoallergenic, making them suitable for long-term wear.
