Digging around in the dark pockets of a camera bag is frustrating. The ToolPak™ is designed to help solve this problem. It will hold filters, batteries, pens, pencils, screwdrivers, a small notepad and most of the small accessories that are difficult to find when you need them. It folds and closes with Velcro® so it will fit into most camera bag pockets. It is made of Tamrac's exclusive Windowpane-Mesh™ so the contents are easy to find. Most of Tamrac's Pro Series camera bags have attachment systems designed into the ZipDrop™ pockets so the ToolPak™ can be attached as a component of the bag.
