Six Syain blues harp set with a white plastic case. - Model Name: Syain - Quantity: Set of 6 - Color: White - Material: Metal and plastic Set includes keys A, B, C, D, F, and G. Purchased about 10 years ago and used a few times, but some keys are almost unused. They were all stored carefully in the case. I am selling them because I purchased harmonicas from a different manufacturer. I checked the sound, and there are no problems, they sound the same as when I bought them. Thank you for looking.
