These Micro-Thin Steel shafts present a smaller profile to incoming darts than regular shafts which means that you will experience fewer deflections away from the board. They are extremely light which reduces the weight at the rear of the dart and makes the darts easier to throw. If your throwing technique causes the back of your dart to dip towards the floor, then these shafts may the answer to your problem. Available in Short (550678) or Medium (550679) lengths. One package includes 3 shafts.
