ROKR Magic Piano Mechanical Music Box 3D Wooden Puzzle | ROKR Magic Piano 3D wooden puzzle AMK81 is the latest product in the Mechanical Music Box series, designed on the basis of a hall-of-fame concert grand piano, with a self-playing interpretation and elegant self-playing keys, adding a touch of mystery to the classical flavor. 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 body of the piano replace the original legs of the piano and play the role of support and fixation. The lid is made of transparent acrylic and is embellished with intricate patterns that look like crystal. The exterior of the piano is covered with a large number of beautiful Victorian ornate and elegant patterns and reliefs. Inside, the body is constructed from a heterochromatic gear set with vintage brown six-petaled flowers – the flowers rotate slowly with the sound of the winding knob, making it a magnificent and elegant instrument. The precision mechanics are cleverly concealed inside the body, driven by a gear set that makes some of the keys rise and fall on their own, adding a touch of elegance to the entire music box.
