Made of lightweight aluminum, each Silvalume hook undergoes a special anodizing process that etches away all surface impurities. In addition, each hook is heat treated for strength and durability and polished for a velvety smooth finish. Each size is color coded so you can find the size you need at a glance. The vinyl case is perfect to store your hooks safely. The in-line head helps reduce wrist motion for fatigue free crocheting and helps you maintain a more consistent gauge. Each gift set contains six hooks in US sizes 3.75 mm, 4 mm, 5 mm, 5.5 mm, 6 mm and 6.5 mm.
