These needles are for an older Jones vibrating shuttle sewing machine. They are about 1.518 inches long and have a full round shank. <u> We are selling six of them at a time.</u> They are Schmetz 12.05 needles and in size are 90/14 which is a medium weight / size. That means that they are a good over all and very usable size / weight. <b>Please note that these needles are the equivalent of a Singer size 16x1 and will also replace a small to medium size / weight Singer 128x1 needle.</b> When these needles are gone, there simply are not any more available.
