The needle is topped with a gray band for wovens and green band for knit and the inner bands shows the size. Blue is 14 and orange is 11. The needles are universal and have been used for the last 15 years in Singer machine embroidery and regular sewing. The chromium works well with the needle threaders because of the wide embroidery threading eye.
In the future Singer is converting Chromium needles to the multi brand Inspira needles to service all 3 brands of Singer, Viking and Pfaff. Right now while they last, I have limited Singer chromium branded needles. Some needles are loose and packaged in an envelop, some are in the traditional yellow package and some are in the red packages but all are the same style 2000 chromium needle.See the new Inspira multibrand needles
