Here’s a different kind of accessory – a money clip that doesn’t look like a money clip. The Invisible Money Clip is actually a sticker that you attach to the back of a dollar (or Euro, British pound or whatever currency you prefer), and the magnets in the sticker turn that bill into a money clip. It keeps your money together with additional bulk or obvious clip. Not sure if or how you would remove the sticker from the original bill so I would include that currency in the cost of the clip. The Invisible Money Clip retails at $9.95. They also offer custom printing if you want to include your logo, business information or special message.
