The outside of the box can be individually decorated using the enclosed stones. In addition to the music box measuring 14.5 x 13.5 x 8.5 cm, the set includes over 470 colorful mosaic stones, 180 sparkling rhinestones, and instructions. Gluing the decorative stones onto the given patterns combines creative design with practical storage for small treasures.
