The Stingray grand piano is made especially for the occasion of the 155th anniversary of the PETROF company. Its dominant design motif is the decoration of its specially shaped legs with inlaid pieces of coloured leather from the stingray. Stingray skin will paralyze your senses. It is an incredibly hard and durable material, but fine at the same time. Its appearance resembles small beads that were embedded next to each other by nature itself. The diamond on the ray’s back is unique, just like the fingerprints of the master who is responsible for building of this instrument.
