This USB memory is called the ‘Flashbag‘. So far so good, but what is unique with this product is that it gets inflated when you fill it up with data. When the USB memory is full, the flashbag looks like it’s going to explode. It’s only a concept model, so you can’t buy it yet though. Interesting idea and product, or what do you think?
