This is a ligature for saxophone mouthpieces made by Aizen, a domestic mouthpiece manufacturer in Japan. I didn't have many opportunities to use it, so there are no noticeable scratches or stains. It has this antique color from new. The size is freely adjustable, and from what I've tried, it can be used on alto (Selmer) to baritone (Meyer) saxophones. The tone is somewhat dark but has a good crispness, and I think it's suitable for jazz. It's very easy to play. It comes with four screws, and you can enjoy different tones by attaching them. The screws included with this product are large and small bronze, and large and small brass. There are no titanium screws. Please refer to the instruction manual for details. I liked it very much, but I have decided to mainly use metal mouthpieces, so I am selling it.
