This is an unofficial version of the Stubby LTT screwdriver, which comes with a built-in storage compartment for five bits. During multiple tests, no matter how hard I pressed on it, the screwdriver remained intact without any signs of breakage. The metal components, known as "bit extension rods", are commonly used in power drills and cost between $2 and $5. They are widely available in the market and easy to purchase. If you encounter any problems or have questions during use, feel free to contact me privately at any time. I'd be more than happy to assist you
