  • Twisting, damaging, or pressing the cord may cause abnormal burning(fast burning, burning failure, etc.).
  • lf the cord is applied with slurry-state fireworks composition, please check the effect of the solvent before use. The solvent may cause abnormal burning (fast burning, burning failure, etc.).
