Sigikid music boxes have system! Almost every music box from the sigikid range has a safety zip on the back. You can open it according to the instructions and remove the game mechanism. On the one hand, the music box is easier to wash, but on the other hand, it is also possible to change the melody or, if necessary, to completely change a piece of music that is getting old. Today, you can choose from a variety of different melodies. These are well-known lullabies such as “Brahms lullaby” or “LaLeLu” on the one hand, but also modern pieces such as “Beauty and the Beast” or the “Star Wars” melody on the other. Each movement is delivered with a red pull piece. The sigikid swap features are often incorporated into animals from other brands as well.
