Mô tả

Its size is the only thing that makes the Bora a small instrument.
As soon as the hammers hit the strings, you will discover its wonderful, rich and surprisingly powerful sound.
Once again we have put the very best materials, technology and design features of concert instruments into its construction.
Its potential greatly transcends its actual size.
Professional players favour it for practice purposes and domestic use.
