This is a Denis Wick mouthpiece for French horn. It's been in storage since I rarely use it now, as I mostly use a different mouthpiece. Therefore, it appears to be in relatively good condition with no warping (this is just my personal opinion). I cleaned it with hot water and baking soda before listing it. However, as it is a used item, there are naturally some minor scratches. Please understand and agree to purchase it as is. I plan to use recycled materials (bubble wrap, cardboard, envelopes, etc.) for packaging. Returns are not accepted to prevent product substitution.
