USB drives come with thousands of designs and colors; some of them are extraordinary weird. But I like this USB drive so much, it is awesome. It just looks like a normal USB drive when it is new without data. But it inflates with its storage and the size of the USB drive blows up like a balloon when the storage is full.

This USB storage device that swells or blows up according to the storage space occupied. What is the magic behind? Well, the designer uses a micropump to make it happens, as simple as it.

So with this funny feature, without plugging into your notebook or computer, you can know whether your USB drive still has available space for storage, by looking at its size.

Very sweet idea. I am looking for one also but I don’t know where to buy, so bad!
