Skacel's Addi Click Bamboo Set combines the beauty and warmth of bamboo with the German engineering of the Click design. Insert the cord into the tip, twist and release! Made from the finest bamboo, you'll love the ultra smooth Addi Natura tips and the snag-free connections. No more buying what you already have or needing what you don't! Each set includes 8 tip sizes: US 4 - US 11; 3 cord lengths: 24, 32, and 40 inches; a connector piece (for lengthening cords); and a very nice needle case.
