Silvalume is a soft pastel colored aluminum hook which is polished for extra smoothness.
These hooks have the biggest size range in the Susan Bates label. 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. The famous in-line head helps reduce wrist motion for fatigue-free crocheting and helps maintain a more consistent gauge.
