A ring closing plier is a specialized tool used in body piercing studios and jewelry making to securely close captive bead rings (CBRs) and other types of jewelry rings. Here are the key features and details about ring closing pliers:

1. **Purpose:** Ring closing pliers are designed to safely and effectively close jewelry rings without damaging the metal or the jewelry piece itself.

2. **Design:** These pliers have a unique design with small, grooved jaws that allow them to grip the ring securely. The jaws are often curved to fit the shape of the ring, providing a controlled grip for manipulation.

3. **Material:** Ring closing pliers are typically made from stainless steel or surgical steel. These materials are chosen for their durability, corrosion resistance, and suitability for sterilization, ensuring they can withstand frequent use in professional settings while maintaining hygiene standards.

4. **Usage:** Piercers and jewelers use ring closing pliers by positioning the ring between the jaws and gently squeezing the handles. This action effectively closes the ring, securing beads, charms, or other jewelry components in place.

5. **Versatility:** They are versatile tools used with various types of rings, including captive bead rings (CBRs), segment rings, and other types of body jewelry rings. They are also used in jewelry repair and modification.

6. **Professional Use:** Ring closing pliers are essential tools in piercing studios and jewelry workshops. They facilitate the installation and adjustment of jewelry with precision, ensuring a comfortable and secure fit for the wearer.

7. **Hygiene:** Like other piercing tools, ring closing pliers undergo sterilization procedures, such as autoclaving, before each use to ensure they are free from contaminants and safe for use on fresh piercings.

In summary, ring closing pliers are essential tools for professionals in the piercing and jewelry industry. They provide precise control and safety when closing jewelry rings, contributing to a professional and hygienic environment for piercing procedures and jewelry adjustments.
