CAUTION: For outdoor use by adults only. Store extra strikers in protective sleeves after use to keep dry. Store matches separately from strikers to prevent accidental ignition.
For lighting a match, it is ideal if the striker is a firm surface which can usually be achieved by just closing the box.
If striker and box become wet, the striker will still work, but needs to dry first so that the surface is once again firm. Use a spare striker until then.
If matches become wet, just wipe dry before use.
Strike away from the body or in a downwards position. Be careful of bystanders.
Be careful when striking the match since sparks can fly off the igniting head.
After using the match, run it in water to be certain that it will not light anything else on fire.
