J. Stockard offers this wire not only as another option for fly tying wire, but also because of Sybai ’s colors. They cover a wide range and the shades are very cool! We carry 3 sizes, equivalent to UTC's X-Small (0.1mm), Small (0.2mm), and Brassie (0.3mm). Those are the 3 most popular sizes of UTC wire, and all are available in an absolutely awesome color range. This wire will work beautifully for all of your wire needs.
