The ROKR Magic Piano 3D Wooden Puzzle AMK81 is the latest product in the Mechanical Music Box series, designed on the basis of a reverb-of-fame concert grand piano. It features a self-playing interpretation and elegant self-playing keys that give it a touch of mysterious classical flavour. The product features a vintage look and decoration, with the main body consisting of a classic grand piano and magical antique books. The magic books stacked under the piano body replace the original legs of the piano and play the role of support and fixation. The lid is made of transparent acrylic and is decorated with intricate patterns that look like crystal.

The outside of the piano is covered with a variety of beautiful Victorian, ornate and elegant patterns and reliefs. Inside, the body is made of a heterochromatic gear set with six-petalled vintage brown flowers - the flowers rotate slowly with the sound of the winding knob, making it a magnificent and elegant instrument. The precision mechanism is skilfully concealed inside the case and is driven by a set of cogwheels that allows some of the keys to raise and lower by themselves, adding a touch of elegance to the entire music box.
