This is the Chukan Strap BBS-1 tuba strap. I used it once for a concert where I had to play the tuba standing up. I didn't use it many times, but since it's leather, there are some stains, wrinkles, dirt, and areas where the leather color has darkened. I have a small build, but I was able to stand and play it securely. I won't be using it anymore, so I hope someone who needs it can use it. This is a used item, so please purchase it only if you are satisfied with the condition. 【Size】 Length: 86-106cm * When the belt holes are at the shortest and longest settings. I don't know the strength at the longest setting, so please judge for yourself. Belt width: 2.8cm Shoulder pad width: 5.8cm Leather thickness: 3.5mm * Measurements are approximate. There may be some errors. Thank you.
