We're all so used to seeing promotional swivel-style flash drives that it's sometimes easy to forget that USB keys can come in a variety of unique shapes and sizes. In fact, if you can think of something, chances are someone has crafted a memory key in that exact style. Check out some of our favourite kooky and bizarre USB flash drives below!

Unique Promotional Flash Memory Keys

5) Katana USB Flash Drive

If you're into traditional swords or just love a unique Japanese-style product, this incredible mini katana USB memory key would be perfect for you. It comes with its own matching "stand" to hold the key in place when you're not using it.

4) USB Wooden Pegs

We stock promotional wooden peg USBs, but we thought they deserved mention on this list as well! You can clip them to clothing or bags to make carrying them super simple. When you're ready to access your data simply plug them into your device. Best of all, unlike the plastic USBs on this list, we can engrave your design directly into the wood on these - very stylish.

3) Custom Drink Shaped Memory Keys

Although the bottle-shaped USB drive pictured is for Gatorade, you can make these drives into any custom drink bottle or confectionery product shape that you like. These USBs make awesome promotional items to help market your product or to get your brand noticed. Load them with images or price lists and give them to your distributors. Very versatile!

2) Serenity Shaped Flash drives

This one is for the Browncoats out there! A sturdy metal USB flash drive with all the fills in the shape of the ship Serenity from Firefly. All sorts of geeky crafts are available online as flash drives including the Millenium Falcon and Death Star from Star Wars, and individual Star Trek ships! Although these products are chunkier than the others, they're a talking point and will draw attention easily.

1) Avengers Assemble USBs

And here's our final pick, which is technically four different flash drives but look at them! Each of these devices is shaped like a different element representative of the male Avengers from the MCU (for some reason Black Widow was left out of this set, despite being the character who would probably require USBs most in her everyday work). Iron Man's mask, Hulk's fist, Captain America's shield, and Thor's hammer Mjolnir, are each shown here as totally functional flash drives.

Bonus! Ninja Star Flash Drive

For the more adventurous out there we can't get past this shuriken or ninja star USB flash drive. Take off one of the four points to expose the USB drive element for plugging into your computer. It just goes to show that pretty much anything can become a kooky and crazy USB drive if there's a market for it!
