USB Memory Direct creates some of the best USB products I've ever seen! Their quality and quantity of drives are by far one of the best out there.
They created for me here SWM Custom Flash Drives. These are USB 2.0 8gb but ... they can create for you USB 3.0 drives all the way up to 128GB! I mean that's unheard of. I'm a longtime WHCC use but even they don't have that option (that I know of).
They can create for you USB drives in multiple wood, plastic, rubber, and metal styles.
