If you’re a builder, plumber, or handyman, you might need a tool you can carry with you on the go. The SO Design Alt Precision Screwdriver Pen Portable Worker’s Tool is designed for such occasions. It might look like an ordinary pen, but it features eight steel alloy bits inside. Each of these elements allows you to tackle any task at hand. Also, with a variety of sizes to choose from, it ensures you always have what you need with you. As a result, you don’t have to carry a large bag of tools whenever something needs fixing. Simply remove the cap and screw on the desired size to turn the pen into an installation tool. When you’ve completed the job, simply store the bits inside the refillable pen to keep them safe.
