A Picopad consists of 15 sticky notes and one tiny pen, that are designed to fit into the credit card slot of your wallet. The pads themselves are made from a cardboard-like material and come in a variety of colors. They feature two small push-out tabs to make it easier for you to pull it out of your wallet. There’s one on the long side, and one on the short side, making it possible to use with top and side loading wallets. See more details in this review by OhGizmo! or on the Picopad home page. They are priced at $3.99 each.
