vintage crochet hooks for making crocheted lace, LeeWards case set of tiny steel crochet hooks

Vintage set of tiny steel crochet hooks for lace making, made in Japan for LeeWards. Sizes range from a 14 (so tiny!) to a 00 (pretty small). The second largest hook (size 0) is missing, but apart from that these don't appear to have been used. Green vinyl or plastic case is showing some age, hooks look good.
