Color coding makes cable stitching easier. SET CONTAINS : L ☒5.50mm×94.0mm M ☒4.50mm×94.0mm S ☒3.25mm×94.0mm Package size : 65mm×120mm×7mm Net weight : 12g ●One side of the needle is color coded. ●The reason for this is that you can distinguish between the picking point and the knitting point of the needle. ●Also, you can recognize at a glance when the stitches have become twisted. ●The point of each end of the needle is different and can be applied according to preference. ●One end is round and color coded, and the other end is sharp. ●The middle section of the needle is narrower, and is tapered from circle to square outwards from the middle. ●This is to prevent stitches from slipping off the ends of the needle. ●Each end of the needle has flat surfaces so that the needle will not roll off the work surface when not in use. ●The needle is small enough and straight enough to be held comfortably in one hand, so need not be picked up each time it is required.
