These hooks have the broadest size range within the Susan Bates family of hooks. Made of lightweight aluminium, each Silvalume hook undergoes a special anodizing process, which etches away all surface impurities. In addition, each hook is heat-treated for strength and durability and polished for a velvety smooth finish. Our famous in-line head helps reduce wrist motion for fatigue-free crocheting and helps you maintain a more consistent gauge. This package contains one 5-1/2in hook.
