Both movement and vibration are live shrimp! "Shrimp"... It lives in any field, is easy to catch for the bass, and is delicious. It is obviously a favorite of the bass to eat. Drive shrimp realistically expresses even the minute vibrations that occur when shrimps move while moving thin limbs in a busy manner. Ultra-high speed vibration of the reverse hand generated during fall and swimming is transmitted to the legs, beard, and uniquely shaped flat tail to quiver the whole body in small pieces, the shrimp itself scratching the water while drifting in the water.
