Thank you for viewing! The hoops are made of soft metal, so the opening can be easily opened and closed with your fingers. You can adjust them to fit the thickness of your earlobes, allowing you to wear them comfortably without feeling pain. The parts that directly touch the skin are coated with resin (transparent resin) and covered with silicone catches, so those with metal allergies can wear them with peace of mind. Hoop diameter: Approximately 10mm Wire width: Approximately 0.9mm Total length: Approximately 18mm ▼How to Wear▼ Gently pull the opening of the hoop from both sides to open it slightly, insert it from the thinnest part of your earlobe, and move it to your desired position. Once you've found the right spot, narrow the hoop opening to a comfortable fit. ■ We make each piece with the utmost care and attention, but due to the nature of handmade items, they may not be exactly like mass-produced products.
