Veevus 200 Denier Thread Black
You wont break this GSP ( Gel Spun Polyethylene) thread, its possibly the strongest thread available. Use it for packing down tight Deerhair so that it glides through the hair and cinches down tight. Wont break or even cut easily, great for flies that take a long time or when the razor gets that little too close. A generous sized spool available in black.
