What is yellow circle match?

As an AI language model, I do not have any specific information about a yellow circle match. However, I can provide you with general information about matches:

A match is a tool for lighting a fire in a safe and controlled manner. It typically consists of a small wooden stick or dowel with a combustible tip that is dipped in a flammable substance, such as phosphorus. When struck against a rough surface, such as the striking pad on the side of a matchbox, the friction generates enough heat to ignite the tip of the match.

Matches come in different types - wooden, paper, and safety matches. Wooden matches are the most common and least expensive type of match. The match head is coated in a chemical mixture that includes sulfur and an oxidizing agent. Paper matches are thinner and burn faster than wooden matches. Safety matches are known as the self-igniting matches. They were introduced in the late 1800s and have a safety feature that prevents accidental ignition.

Overall, matches have been an important tool for starting fires for centuries, and have played a critical role in human survival and development.
