【Manufacturer】 Tom Crown 【Product Name】 Straight Mute for Tenor/Tenor Bass Trombone 【Material】 Aluminum 【Manufacturer's Suggested Retail Price】 16,720 yen I used this for 5 years when I was in the school band. There are minor scratches and small dents from use. There are no noticeable large scratches or dents. I believe it does not affect the performance. It will be wrapped in bubble wrap and shipped in a cardboard box. Please refrain from purchasing if you are concerned, as this is a used item.
