This is a curved needle for the Wheeler and Wilson and the Elleptic sewing machine. They are size 2 1/2. Please note that this may not be the exact needle that you receive but I guarantee that it is marked W&W and that it is the curved needle. We are selling one of them at a time. I am only photographing one of them and will sell them until they are all gone so do not miss out on this rare item. When they are gone, there simply are not any more available.
