When you are looking for Flash Drive Packaging, you will find that there are so many options available to you. So it would probably help to have an idea as to the type of image that you are looking to achieve. Normally the USB stick will sit inside of a moulded plastic inner, so you can have many sizes of outer case. It comes down to the image that you are trying to portray. If you are trying to promote something of a lower value, then perhaps packaging is not actually something that you need. As USB sticks can often have there own protective caps, and are often printed with a corporate logo.
