I've also thought about questions. Labels on both sides cover the hole around the bottom. Peel off the labels from both sides around the bottom and you will see a crescent shaped indentation on one side. Grasp the bottom, press your thumb against the crescent and pull up on the opposite top of the plastic box. If you lift the lid, you can see a series of stops (bulges) on the left side. The box is easy to open and close. First I wanted to know why the chainsaw wasn't there to open it. I think the ADVANTAGE OF THESE drill bits is that they are all one piece. My research revealed that the titanium and other drill bits that were "attached" to the shank all broke. I only use them around the house with my B&D electric screwdriver and am very happy with them.
