● Please refrain from purchasing if you are concerned, as this is a used item. This item was used by my mother. She is selling it because she has stopped playing the harmonica due to her age. I asked my mother, but she doesn't know the product name or model number. ● It can store four 21-hole harmonicas. ● There is fraying on the side of the case (see photos 4 and later). It will be shipped via Yu-Packet Plus.
