Straight Mute for French Horn

This is an Ionbal straight mute for horn.

It is very sturdily made, and the manufacturer is used by orchestras such as the New York Philharmonic.
Due to its sturdiness, it is slightly heavy.
I believe it produces a clear sound.

It has been used for several years, so there is some wear on the cork and scratches, but it does not affect playing.

It will be carefully wrapped in bubble wrap before shipping.
Thank you for your consideration.

Please note that this item is also listed on Carrott, so we will prioritize the first buyer.
