Look sophisticated all while storing 4,194,304 Kilobytes (4GB). These cufflinks will hold your clothes together and keep your data at hand. These cufflinks are great for storing all forms of data, including documents and spreadsheets for business meetings and photo slideshows for your family reunion and get-togethers. The cufflinks are shiny stainless steel for durability and beauty. Both links look similar but one pops open to reveal a USB A plug that you can slot into any computer. The other link does not open (it's just designed to look like the one that has the storage inside). They are perfect for the business man or woman that regularly needs to carry files of information with them. You'll never be without functional fashion again because these elegant cuff accessories will keep all of your important files right at hand. Literally.
