Kaerntner Full Double Horn Open F Tube, B♭ Tube Switching, with Mouthpiece I purchased this, but there was a defect in the product upon arrival, so I am selling it as junk because I am buying a new one. *Sound check confirmed ◎ → It produces sound, but there are several places where the solder has come off. (I have confirmed 4 places) The part that supports the tube is missing, and there is a part of the tube where air is leaking (reinforced with vinyl tape). Please check the photos for details. *The tubes can be inserted and removed, but it is quite difficult. Part of the rear tube does not go in all the way. (There was no problem playing it) *The instrument body feels slightly warped. For those like me who want to buy it for practice and then buy a better one later, or for those who want to maintain and repair it themselves and use it for a long time, this product is for you. *Accessories ・Kaerntner case ・Mouthpiece *The appearance is relatively clean, but please understand that there may be fine scratches and dirt that cannot be captured in the photos. Immediate purchase is OK. Thank you. *Because it is a junk item, it is listed at a lower price than average. There are no plans to lower the price. It is recommended for those who can take it for maintenance or who can do the maintenance themselves. *I have attached photos of the areas that seem to need repair.
