The transparent material clip should not be missing on any tying desk. It is perfect to hold material for a loop & in combination with the flip tool it simplifies the preparation or blending any kind of material immensely! The clip has good tension strength and holds everything where it is supposed to be. The width of the usable area is 6cm, enough space to place material for dry flies up to small streamers in a single loop. A very good quality from Germany at a fair price.
