I purchased several of these for students and for practice. I am selling the spares (unused). They are small and convenient to carry. After use, they are valveless, so you can rinse them with running water, shake off the water, and let them air dry, making maintenance easy. Why not start it as a hobby? The drawbacks are that it has 10 holes (usually 12 holes) and the low notes are weak due to its small size. The advantage is that it can play chromatic notes, so you don't need to buy them by key like a blues harp, and you can play most songs with just one. Note that there is a knack to playing the low notes. It is not a malfunction, so please be aware of this. For those who want multiple, I will deduct 200 yen for each additional one. For basic knowledge and playing techniques, please refer to the following introductory book published by Suzuki Musical Instrument Manufacturing: (Upgrade to SUZUKI's high-end instruments when you improve) https://www.suzuki-music.co.jp/app/uploads/chromatic_harmonica_kiso.pdf Level: Beginner Type: Harmonica
