Thank you for viewing. This is a Backun Barrel MoBa Grenadilla for Selmer, 62.5mm. I am selling it because I no longer use it after changing instruments. I used it with my Selmer Signature B♭ clarinet. I used it in conjunction with the included barrel, so the frequency of use was low. Although it is for Selmer, can it fit other brands depending on joint adjustments? I would appreciate it if you could research that yourself. It produces a softer tone, and the blowing feel is lighter compared to the included one. The box is from when I purchased it, but as you can see in the photos, it has some folds. Please feel free to consult about a discount. I believe it is a beautiful item, but it is a used item stored at home, so please purchase it only if you understand.
