Here’s another jewel-like collection USB flash drive from Empty Memory, Transparency USB Stick. Each piece is made of high-quality 316 stainless steel and hand-polished by craftsmen, it is then finished in various colors. It’s a gorgeous USB 3.0 drive with 16GB capacity, some people don’t buy this device for its space rather for its beauty. Each unit features physical emptiness in its sculptural form, just like Structure USB Stick, the design creates a metaphor that you can fill the space with your own memory.
