Cautions in handling
- Please be sure to check the burning time before use since it may change due to long-term storage or moisture absorption.
- 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.).
