Musical keys

 

— toys of this type usually take the form of a key ring with keys attached to it. At the same time, the key fob device is similar to “adult” keychains; the design usually has a ring on which the keys are put on. The keys themselves are usually ordinary pieces of plastic, intended only to be put on and removed from the keychain. Despite the apparent simplicity, such a device perfectly develops fine motor skills, and also teaches the baby the basics of handling adult keys. And in the key fob, buttons and electronic filling are often provided, allowing the toy to make various sounds — melodies, car horn, engine noise, etc. This provides additional entertainment.
