These fishing spinnerbait bodies are made of high-grade brass, which has high wear resistance, good impact resistance and corrosion resistance. The streamlined bullet design can reduce friction in the water, make the spinner easier to move, and provide lure with better balance and stability. The surface is polished which can increase attraction to fish by reflecting light, generating noise when it collides with spacer beads, both in freshwater and saltwater. The essential component of lure spinner allows you to make your own spinnerbait, inline spinner, tail spinner or rigs.Targeting for bass, crappies, perch, trout etc. Qty.:20pcs Weight:12.5g,8.5g,5.3g,5g,3.5g Length:28mm,25mm,20mm,18mm,17mm
