Silvalume Aluminum Crochet Hook E-4

Made of lightweight aluminum, each Silvalume hook undergoes a special anodizing process, which etches away all surface impurities. Each hook is heat treated for strength and durability and polished for a velvety smooth finish. Head helps reduce wrist motion for fatigue free crocheting and helps you maintain a more consistent gauge. Hooks measure 5-1/2 inches.
