Tetra Works Bivi

Authentic micro vibration "Vivi" with a hollow body.

The body with a high specific gravity design realizes excellent casting performance and quick fall, and is effective as a search bait for efficiently exploring a wide range.

It has a high range keeping power and is ideal for points with high scaffolding such as embankments and tetras.
The 3mm tungsten ball built into the abdomen as a sub weight also acts as a rattle ball by allowing it to move freely to the left and right in the room. It appeals to the target with a rattle effect that is not found in metal models and solid models.
