This listing is for one crochet hook, size 20 / 0.6 mm.
This is a really tiny crochet hook, used for very fine yarn or thread. I think it would also work nicely to add beads to a knitted project as the hook is small enough to easily fit through a size 6/0 seed bead. Crochet hooks this small are hard to find.
The crochet hook comes with a cover to protect the hook end when it is in your project bag.
