Info From Manufacture:A tandem of cajon and foot pedal that transports in itself.The Drum Box model is a new concept in the world of the caj³n: in addition to the front panel this caj³n features an extra side surface which is meant to be played with the patented pedal that is on De Gregorio's catalogue. This comes in the original box and with everything pictured. The pedal works perfectly with no issues. It does not affect the sound or attaching or removing the door. They are around the edges on the top and bottom. Also, on the back of the door, there are two small pieces of wood that are missing. There is one on the door, on the bottom where the screw holds the door on and there is one on the side. This is a used Cajon that comes in the original box.
