Strike-anywhere matches are a type of match that can ignite when struck against any rough surface, not just the specially coated striking strip found on traditional matchboxes. This feature makes them convenient for outdoor use or in situations where a striking surface is not readily available. These matches are typically made with a mixture of chemicals, including phosphorus, which is responsible for their ability to ignite easily. However, due to safety concerns, the production and sale of strike-anywhere matches are regulated in many countries, and they may not be as widely available as standard matches.
