You can find various USB flash drives and several great idea about concrete like the game console architectures. But the concrete brick USB flash drive appears for the first time.
I’m afraid the unique USB drive appears for the first in the world instead of only at Gadgetsin. Unfortunately these USB flash drives which we’ve seen are just several prototypes, which are designed by Shu-Chun Hsiao. The heavyweight USB flash drive is made from concrete, and it’s shaped as a cement brick. The storage capacity is engraved on the surface of the brick, which is also the weight of the USB drive.
It seems the concrete USB flash drive series has three types, 64GB, 128GB, and 256GB. Which do you think is more suitable to girls? We think it should be the 256GB. undoubtedly the USB flash drive is a very nice defensive weapon.
