Silvalume needles have the broadest range within the Susan Bates family of knitting needles. Made of lightweight aluminum, each Silvalume needle undergoes a special anodizing process that etches away all surface impurities. In addition, each needle is heat treated for strength and durability and polished for a velvety smooth finish. This package contains two 10 inch long single point knitting needles. Size: 13/9mm. Imported.
