This is a C-tuned TOMBO Premium 21 harmonica, but the reed for the middle "E" note on the lower reed plate is broken and missing (as shown in the red circle in photo 2). It cannot be used as a harmonica in its current state. Due to the missing "E" note, this is being sold as junk. The case and everything except the harmonica's reed plates are in good working order. It can be used if you obtain a replacement reed plate and install it on the body. To reiterate, this harmonica is unusable as is. Please be aware. Do not mistakenly purchase this thinking it is in good condition. Given these warnings, returns and complaints will not be accepted. - Brand: TOMBO - Model Name: Premium 21 - Key: C - Model Number: No.3521 - Type: Neo Standard Harmonica Thank you for viewing.
