WM-BF22 Opening

The Sony WM-BF22 case does not employ any screws, and instead uses plastic locking tabs, which are extremely difficult to separate. The back lid fits so tightly and precisely that at first it can appear that the case is sealed. For some of you, it will take seconds to open this, and the rest, the terms of your natural lives.

The Secret

The secret to opening this requires you to have an old plastic top-up card, which you have to cut into thin strips. You simply need to wedge the strips between the gaps at the seam indicated by the arrows in the diagram above. Of course, I make it look easy, and I managed to open it without causing a single scratch or breaking any tabs.
