This is a listing for a set of three used TOMBO Dragon-Fly Brand tremolo harmonicas in the keys of C, G, and F. All three are 21-hole harmonicas. They all produce sound without issue. I have two other C (C major) harmonicas, so this one hasn't been used much and is in clean condition with no noticeable scratches. The G (G major) harmonica has been played frequently, so while there are no scratches, there are some scuffs that are visible depending on the light. The F (F major) harmonica's case is crushed, so it will be sent in a simple pencil case. It has been played quite a bit, though not as much as the G harmonica, and has some scuffs. Images added. Two cleaning cloths were found, so they have been added as well. Please review the images and consider the above information before making a purchase.
