Hanak Micro Rings provide a smooth connection between two sections of leader. Their surface is designed to maintain knot strength. They feature a black nickel finish. The 2, 2.5, and 3 mm diameters correspond to 9, 13, and 18 kg of breaking strength, respectively. Each size comes in a pack of 10 micro rings. The 2 mm size is sufficient for fine rigs; use the 2.5 or 3 mm sizes when strength and ease of handling are more important than maximum discretion.
