What are the Different Types of Key Chains?
Key chains are handy for keeping track of keys, but they are also functional in other ways. Some key chains have built in flash lights so you can see the door when you are trying to unlock it at night, while others have personal alarms in case you need to alert those around you that you are in trouble. There are also those that come complete with other self-defense mechanisms, such as “punch knives” or pepper spray.
