A bobbin holder with a head that is about 10mm0.4inch longer than the Midge regular size.

By moving your hand slightly away from the bobbin holder, the tension that winds the thread around the hook becomes more subtle.
It is recommended fortiers who frequently cut ultra-fine threads during tying.
It is also recommended for tires that are difficult to grip with a regular size bobbin holder with large hands.

Uses high-quality ceramic (zirconia) tubes that prevent threads from breakage.
A dedicated bobbin threader is included.
By opening and closing the arm, adjust it so that the appropriate tension can be obtained.
When applying strong tension to the thread, be careful not to apply too much load to the ceramic tube and break it.
