This collection covers ROKR mechanical music boxes (hand-cranked, self-playing, and visually stunning once assembled), wooden guitar and piano scale models that look at home on any desk or shelf, and music-themed 3D wooden puzzle kits that double as display pieces. Music boxes in particular tend to land well with people across a wide range of ages — there's something about watching gears and comb pins work together to produce a melody that makes sense to anyone who cares about sound.
