Luxury phone maker Gresso has designed some beautiful looking wood-encased USB flash drives. The drives are like jewelry, designed to be hung around your neck. These USB flash drives are made from mahogany and African blackwood, laser engraved, and encrusted with white diamonds. They seem ideal for the well off person who needs a flash drive on them but is prone to losing things. Both the replacement cost and the strap around your neck will ensure that your drive isn’t going anywhere.
