Casio CTK-720 electronic keyboard with 61 keys, built-in speakers, an LCD music-information display, and labeled tone, rhythm, song-bank, and lesson controls. Close-up photos confirm the model and show the control panel in detail, including the printed USB marking. The black housing and keys show ordinary handling wear. This is an untested keyboard: sound output, individual keys, connections, and all functions have not been checked. A power adapter, music rest, stand, and pedal are not shown and are not included in this listing.
