Veevus G.S.P. is a thin and extremely strong tying thread. It is manufactured of continuous fibers of gel-spun polyethylene (GSP). The thread has been designed with a slight twist preventing it from opening up, and thereby making tying with it a breeze. It lays completely flat and is the smoothest thread to spin hair with.
Also available on 30 denier strength which is equivalent to approximately 18/0 thickness in standard threads. Perfect for small flies.
Each spool contains 75 meter of GSP thread.
