Thank you for viewing (⁎ᴗ͈ˬᴗ͈⁎) This is a synthetic leather protector for French horn, B type, which supports the left hand. - Brand: Galax - Type: B Type - Application: French horn protector - Material: Synthetic leather - Features: Supports the left hand I tried it on once, but it didn't fit, so it's almost unused. It's in beautiful condition, but it has been in someone else's possession once, so please consider this before purchasing.
