For sale is 14 pairs of 13" bamboo knitting needles with various sizes: US1 (2.25mm), US2 (2.75mm), US3 (3.25mm), US4 (3.50mm), US5 (3.75mm), US6 (4.00mm), US7 (4.50mm), US8 (5.00mm), US9 (5.50mm), US10 (6.00mm), US10.5 (6.50mm), US11 (8.00mm), US13 (9.00mm) and US15 (10.00mm). Needles are carbonized to enhance their strength and color (patina). Each size has 2 needles. Sizes in US and metric are permanently etched onto the needles by laser. These needles are first sanded super smooth using the finest sanding paper. They are then lightly hand rubbed with a thin layer of wax to improve the smoothness. While feeling super smooth, one can still sense the texture of bamboo. That makes them very different than lacquered needles. These needles do not have ripples (a common defect with a lot of mass produced needles). Needle points are uniformly shaped. Their smoothness, stiffness and overall quality can meet or beat any world class brands.
