Locktune — Three-Way Locking Music Bank

A wooden build-it-yourself music box and savings bank that turns every unlock into a mechanical discovery. Children assemble the box themselves with a kid-size screwdriver, then open their treasures three ways: turning the rotary dial, sliding in the brass key, or entering a secret digit code. Through the clear acrylic top window, they watch wooden cams, steel latches, and the brass music drum move in real time—each mechanism driving the same latch to pop the lid and play a melody. Coins dropped through the top slot rattle inside, making saving a game. *Note: Internal mechanisms shown are illustrative and may be customized based on selected function options.*
