The BL40 screams sophistication and sleek lines. The body is a glossy black, into which the screen blends in perfectly. The top and bottom have orange detailing, lending a splash of colour to an otherwise dramatically dark phone. There is a line of silver piping running along the sides, taking the phone to new levels of design class.
The front has the screen, and is unmarred by any aberration on the smooth glassy surface. There is a small camera lens on the top right, but it is barely noticeable as it is embedded under the glass. The left side has a dedicated music button and a microUSB port. The right side has the volume/zoom rocker switch and the dedicated camera button. The back panel has the camera lens and the accompanying LED flash. The bottom has the tiny speaker, while the top has a headphone jack and the power button - which also doubles up as the standby key.
The buttons on the sides are also silver and are incorporated into the lines like blips, creating a rather pleasing visual effect.
