LUMI Keys 25-Key MIDI Keyboard Controller

The item is a compact, portable MIDI keyboard controller, identifiable as a LUMI Keys module. It features 25 keys, arranged in a standard piano-style layout, comprising both 'white' (light grey) and 'black' (dark grey/black) keys. The keys appear to be made of a durable plastic material. The overall dimensions suggest it is a compact device, designed for easy transport and integration into various musical setups. The main body of the controller is black, providing a sleek contrast to the lighter grey keys. On the top left corner of the device, there are two circular buttons and a longer, rectangular button, all light grey, suggesting control functions such as power, octave shift, or mode selection. A small LED indicator or light is visible next to one of the circular buttons, which typically indicates power or connection status. A black USB-C cable is shown plugged into the device, indicating its power source and data connection. The brand name 'LUMI' is clearly printed in white capital letters on the top right section above the keys. The visible condition of the device appears to be good, with no obvious signs of significant wear, scratches, or damage. The keys seem clean and intact. This item belongs to a modern production era, likely within the last decade, aligning with the introduction of USB-C connectivity and modular MIDI controllers. The construction appears sturdy and well-finished, characteristic of consumer electronics designed for music production and learning. The unique selling proposition of LUMI Keys is often its light-up keys, which are used for interactive learning and visual feedback, though this specific feature cannot be confirmed from the static image.
