Paraschos wooden neck for alto saxophone. It offers a very warm tone and playing feel, characteristic of wood. While there is some deterioration on the surface of the metal parts and cork, there are no scratches that would cause problems with use. The wooden part appears to be clean. The official website states that it can be used with Selmer, Yanagisawa, Yamaha, and other saxophone manufacturers, but please check the official website for details. http://www.morizono.co.jp/Paraschos%20wooden%20products.htm The octave mechanism seems a bit delicate, so some adjustment may be necessary depending on the model. It will be shipped in a Yanagisawa outer box. Please note that the box is deteriorated.
