Maxtone trumpet 0404. It produces sound. I am a complete beginner, so I apologize if my explanation is insufficient. The finger valves move without any problems. The springs? (or similar parts) also move without any problems in two places. I will disinfect it before shipping, but please disinfect it again upon arrival. My husband apparently bought it several years ago, but it seems he hasn't used it and has just kept it. It was in its original case, but last year, when I took it out after a long time, I thought I didn't need the case and threw it away... Therefore, I will wrap the instrument itself in cushioning material and ship it in a cardboard box. For those who understand that this is a used item, thank you for your understanding. Thank you for looking.
