The Renzetti line of premium bobbins  are a great addition to any tier's tools. These bobbins come in varying combinations of tube lengths and diameters. The standard length tube is 2-inches, the extended length version is 2 3/4-inches. The small diameter tube is 3/32-inch and the large diameter tube is 1/8-inch.

With the exception of the Ultra Midge Bobbin and Lead Wire and Tinsel Bobbin, Renzetti uses ruby tips that make for ultra smooth thread delivery and excellent wear resistance. Customer feed back from The Fly Hatch and others has led them to redesign the bobbin balls. Renzetti's unique tapered protrusion insures maximum thread spool retention. These are really nice bobbins at a fair price.

Note:  The Ultra Midge bobbin with its 1/16'' dia. tube is a nesessary tool for anybody tying small trout flies.
