These solid black domed eyes have a shank and are either inserted into a hole in woodworking projects or used with a retaining washer (included) to fasten the eye to fabric. Each eye measures 15mm (approximately 5/8").
If a larger package is needed, try this bulk set of 20 pairs
If you find the washers difficult to push onto the eye, we suggest heating a cup of water and soaking the washers for a minute or two. This will make them pliable enough to easily slip over the eye shaft ridges. When the washer cools it will tightly secure the eye to your project.
