ESP Hair Stops -Mini 200 units per packet. Available in Mini 4.7mm and Small 6mm. Carefully designed for the specialist carp angler, these hairstops are excellent examples of E-S-P design engineering. Having miniature tapered ends, they feed easily into the smallest hair loop, even one which is wet and has stayed closed. The narrow waisted middle provides a secure seat for the loop and the minature dumbbell shape holds the stop firmly in place.
