Mô tả

The Rococo Gold also possesses the characteristic rounded and romantic tone of PETROF instruments.
What makes it unique, however, is its use of Baroque design, ivory colour and gilded decorative features, making the Rococo Gold ideal for Baroque-style interiors.
We used gold plate for the decoration of the piano.
