From the Norwegian word for happiness, Lykke crafts their Crochet Hooks out of lightweight laminated birch… Happy-making, indeed! In soothing blue colors that shift from light to dark, the Indigo hooks are nice and warm in your hands, and their smooth finish allows stitches to glide along with ease. A black metal cap at the bottom of each hook is stamped with both US and metric sizes for easy identification. Handcrafted in Kathmandu, Nepal, this Crochet Hook Set is housed in a blue denim case and includes 10 six-inch long hooks ranging from US E-4 (3.5 mm) to US M-13 (9 mm).
