Comes with a hook. These have been sitting around for a decade. Used a few times but my hair outgrew them. Branded Curlformers. I bought them in the mesh bag. Washed them and there’s a film on some of them which is either from the soap I used or leftover hair products. Will almost certainly wash out. Suitable for medium length hair. If your hair is just past your shoulders and onto your upper back, it may be too long.
