Solid Brass Self Piercing Round Shaped Garment Eyelet

Garments and eyelets are metal, plastic, or rubber rings that are inserted into a hole made through another material. They may be used to reinforce the hole, shield something from the sharp edges of the hole, or both. Garments are used to reinforce holes in leather, clothing, shoes, and other fabrics. They can be made of metal or plastic, and are easily used in common projects, requiring only the grommet itself, a grommet-setting tool (a metal rod with a convex tip usually sold with the grommets), and a hammer.
Higher-end grommet presses (as shown in the picture) exist as well, though generally a hammer and the garment-setting tool are equally effective for small projects. Their most common usage is to strengthen the holes for boot lacing but they are also good for making corsets and other laced clothing, plus curtains and other household items that require hanging from hooks. The grommet prevents the cord from tearing through the hole, thereby providing structural integrity. Small grommets are also called eyelets, especially when used in clothing or crafting. When using eyelets for crafting, they are generally used decoratively. When used in sailing and various other applications they are called cringles.
