These safety eyes are perfect for your larger felting projects. The eyes are 30mm in diameter with a black centre and clear. These give you the option to add your own colour by adding coloured paper or even foil behind the outer ring. They come with a notched peg to the back for attaching, and caps to place on the peg to secure them in place. Once the cap is in place it is difficult to remove so be sure to position correctly before securing. A drop of superglue can also be used to keep things from moving.
