Preciosa Nacre Round Maxima 12mm Dark Blue Pearl x6

The same thread that's used to make parachutes and sails -- high-tech multi-fibers made from molecularly compressed synthetic materials, make this one of the strongest fibers in the world, while keeping it soft and supple as silk. Color may vary from dye lot to dye lot.

Easy to use, just insert glue into the tip, then press the cord into the tip and let dry.
