Sigikid music boxes have a system! Almost every music box from the sigikid range has a safety zipper on the back. According to the instructions, you can open it and remove the musical mechanism. This makes it easier to wash the music box on the one hand, but on the other hand it is also possible to change the melody or, if necessary, to completely change an aging musical mechanism. Today, you can choose from a variety of different melodies. These are well-known lullabies such as “Brahm's 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 musical mechanism is delivered with a red train piece. The sigikid trading instruments are often also incorporated into animals from other brands. This is possible, but you should pay attention to the size of the work to be exchanged. The sigikid musical mechanisms are 5 x 4.5 x 3 cm in size. This model plays the melody “Do you know how many stars are there”.
