The KAWAI KM-205 metronome provides accurate beats and features volume adjustment. It came with the purchase of an electronic piano. While the metronome itself hasn't been used much, the lid clasp is broken. However, this doesn't affect its functionality. The box has stains and discoloration due to long-term storage. There is no instruction manual. - Brand: KAWAI - Model: KM-205 - Type: Metronome - Features: Volume adjustment switch - Tempo Range: 40-208 BPM Thank you for viewing.
