Set of 4 black solid washers, each measuring 15mm, designed for craft projects. These sturdy plastic washers are ideal for securely attaching googly eyes to various materials. To use, cut a hole in the fabric or surface, insert the eye with the dome facing outward, and ensure the post protrudes from the back.

Suitable for a variety of creative projects, these reliable and user-friendly eyes add a professional finish to your handmade creations. Not recommended for children under 3 years old due to small parts. Each pack contains four washers, providing ample supply for multiple projects.
