Set animal hair that imitates the crayfish's legs and antennae. A slightly constricted design to create ideal movements and vibrations. The waves generated by other parts and the large vibrations of the body are intricately intertwined, creating a more realistic sense of life. The ribs on the back side are easy to hold air and are diffusely reflected in water to appeal. Realistically produce female crayfish and macrobrachium that hang eggs. The thick flat part reliably catches the weak water flow, and the thin inner part vibrates slightly to invite the bite.
