The Mini Spin Wallet Card is so thin, that you can carry it alongside your debit and credit cards, right in your wallet. It is one-fourth the size of a standard card disk-style customized USB drive, so it takes up hardly any space at all. It is a great option for those companies who need more elbow room for graphics and logos than a typical flash drive, but not quite as much as a full sized USB card disk. Length 1.69", Width 1.00"
