You can’t consider the Tool Pen to be just another product because it’s inevitably an entire toolbox condensed in one item. The design is compact, lightweight and portable so that you’re able to carry this tool kit no matter where you go. It has been made using a cartridge system so that you’ll be able to purchase new parts as and when required. That makes it cost-effective and pretty much customized in space saving. Each edition comes with 16 bits which includes a metric hex set and an imperial hex set. An incredible pen style solution as your tool kit replacement.
