Convenient starter set with 25 two-part eyelets plus a setting tool in a clean white finish. The 4 mm (1/8") size reinforces small holes for lacing, tags, drawstrings and craft details. Eyelets are made from rust-resistant brass for durability. To install, interface the fabric at the placement marks, pierce the hole, and set the eyelet on a hard, flat surface using the included tool. Ideal for garments, accessories and paper crafts where a neat, reinforced opening is needed.
