Crafted from natural rosewood, the box retains its distinct, organic grain. Its rounded-square design is polished to a smooth, burr-free finish that feels warm and pleasant to the touch. The material offers a premium, timeless aesthetic and is resistant to warping or cracking.
It features a high-quality Sankyo metal wind-up movement that produces a clear, resonant sound. While the classic melody "Tori no Uta" (Song of Birds) is the standard choice, you can also select from hundreds of other instrumental tracks, such as themes from *Howl's Moving Castle*, *Spirited Away*, and *Castle in the Sky*, as well as Pachelbel's *Canon*.
The exterior of the lid supports the engraving of customer-specified patterns or text.
PS:Made from solid wood derived from natural timber, the material features varied grain patterns and unique forms; consequently, the presence of natural markings—such as knots, dark mineral streaks, color variations, sapwood edges, and ripple patterns—is entirely normal and does not constitute a quality defect.
