Viva/Viva SPIN BAIS/Spin Bias Weight: 0.2 oz (5 g). To suppress the generation of threads that are often found in conventional spinners, we use light tin.

In addition, the blade placed in the front of the body allows for quick rise and not stick to the body even when retrieving at low speeds, it supports a wide range of retrieve speeds.
