F-C BULLET BOBBIN Narrow tube for precise thread control and the meaty "bullet" to hold while tying makes this one of our most popular bobbins. Tube is slightly flared on both ends.
the bullet bobbin is of good quality for the price, good for beginners. However as time goes on and you learn to tie flies it becomes very necessary to have better control of your thread. A branch across the the arms would make this bobbin very stable and to have more control of your thread when your using them.
