This is a horn protector. I bought it because my hands are small and my pinky finger was at its limit. I used it for two years. The Velcro strap was tightened quite a bit, so some parts are a bit fuzzy. It was quite expensive, so I kept it even after I stopped playing the instrument, but I'm putting it up for sale in the hopes that someone who needs it can use it. Please understand that it is used. Thank you very much.
