Made entirely of cardboard, this instrument pops up from a single flat piece into a full size cajon in four easy steps. The structure is stable and can comfortably hold children or adult players, can hold up to 330lbs. Inside is a fixed set of snare wires to provide a crisp snare drum sound. The cardboard material provides naturally deep bass, making the Cajon-2-Go a great, inexpensive alternative to the traditional wood style cajon construction.
