There are times when you realize that it would be a lot easier if your keys, mp3-player, cell phone, small equipment or badge would be a lot easier to keep with you, and use if it was attached to a retractable lanyard. When you are in situations where you need to have that item nearby and you don't want to wear it in your pocket, using a lanyard is the best option for you.
It is the best possible gift idea that you can give to a lot of people because everyone needs a retractable lanyard for fall protection of different electronic gadgets, or just to make it more useful to have something at hand at all times. For example you could use it when you go golfing to attach your ball mark repair tool, so you won't have to find it in your pockets or in your bag every time you need it.
You can easily by retractable lanyards from the internet and you can find them as wholesale with discount prices. That way you can order in bulk and probably even have a personalized image custom imprinted, so all the people you give them to will always remember who gave it to them.
One of the best uses for lanyards of this type is for fishing equipment - you have so much of those little tools and you need to have them easily accessible at all times, and you don't want to drop them. That is where you can use a retractable lanyard for fall protection - it can't drop on the ground because it is attached to a wire that is spring loaded and will retract once you release the item from your hand.
Also if you have a badge that you have to constantly use to get through doors at your work place then using a retractable lanyard is a great way to make it easier. You don't want to be digging trough your pockets every time you have to go through a door, but you can just easily stretch the badge from the lanyard and use it to identify yourself. Once you are done just release the badge and the reel will retract the wire and the badge will be once again ready for use.
Holding your keys, using it for an ID badge holder, or for an MP3 player is just one of the uses that you can use lanyards for and it is up to you to find where you can use it.
