The smooth, rubberized feeling and texture of the Dritz Fashion Grommets provides a professional finish and a decorative detail to garments, bags, purses, and other projects. The grommets include a plastic insert that provides extra stability and support, making the grommets suitable to be used with only 1 layer of fabric. The washer is placed over the insert and applied with the hand tools and a hammer. The result is a smooth finished grommet that is suitable next to your skin or other fabric surfaces. The kit includes 8 rustproof grommets, inserts and washers, plus the anvil and setter tools for application. Machine washable and dryable.
