Acrylic is skillfully hand-mixed to produce unique colors and patterns making each needle tip in this set a work of art. Marblz are lightweight and smooth yet exceptionally strong and durable. The needles boast pointy tips, smooth joins, and a comfortable surface that provides just the right amount of ‘grab’ to allow for easy handling of slippery yarns. Presented in an attractive black and white faux leather case with transparent vinyl which shows off the beauty of these needles, the set includes 9 pairs of Marblz interchangeable needles in sizes US 4 (3.5mm), US 5 (3.75mm), US 6 (4.0mm), US 7 (4.5mm), US 8 (5.0mm), US 9 (5.5mm), US 10 (6.0mm), US 10.5 (6.5mm), US 11 (8.0mm). It also includes 4 Cords (to make 24", 40" & 2 of 32"), 8 end caps, 4 cord keys, and 1 set of cord connectors.
