Flash drives are a great way to promote a business. Most USB flash drives come with a plastic casing. The casing protects the flash drive from damage and dust, although it will not always protect the drive from melting when exposed to extreme heat. A person with a business or organisation who wants people to remember an event or see their logo every time they look for a file or an assignment, may decide that put their logo on a plastic cased usb drive as the best way to promote their business.

Promotional flash drives made out of plastic are generally the cheapest usb drives and can be easily printed and distributed to a large quantity of clients or people. Whether these people are customers, employees or even college students depends on the nature of the marketing. Companies that cater to school or college students may want to order a promotional USB drive or a few thousand.

A promotional USB flash campaign does not do any good unless the drives are handed out. A way of getting good advertising is to donate them to a school or college you want to get customers from. The recipient may never have even heard of your company before. Now, every time he has to work on a school assignment in multiple places, he will see the logo of the promoted business every time he places the drive into a campus computer's USB port.

Plastic promotional flash drives are best when given to large numbers of people so a festival or major public event would be an ideal place to use this method of promotion. The USB flash drives would be taken home by many people and if given out as a free promotional item they would be appreciated more than other more traditional promotional items. They would also be used publically too, at the work place, or to transport information between home and a friend, your logo, your message and your contact details will be taken too, advertising your company to a wide audience.
