Susan Bates Silvalume Single Point Knitting Needles 10" Set - SUSAN BATES-Silvalume 10in Knitting Needle Gift Set. 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. Each size is color coded so you can find the size you need at a glance. The knobs feature a no-roll design and the US and metric sizes are clearly printed on the knob. Each gift set contains three pair of needles in US sizes 6 (4mm), 7 (4.5mm) and 8 (5.0mm). Imported.
