Bassoon Seat Strap KÖLBL Made in Germany Cowhide leather With boot cup (can be used even with instruments without hook holes) Used for about 2 months, 2 hours a week. Total usage time is less than 24 hours, so it's practically new. This is a very good item that reduces the weight on your body when holding the instrument. I bought it with enthusiasm when I started playing again, but I had to stop playing due to health reasons, so I hope someone who can use it will take it. Thank you for looking.
