Plastic thumb rest and thumb hook for Yanagisawa saxophones. (Cannot be installed on Yamaha or Selmer saxophones.) The coaster in the second photo is not included in the sale. Neither item is new; they are used and have been installed on an instrument once. Therefore, both have some scratches. The thumb rest was installed without using adhesive. Please understand that these are used items before purchasing. If you need the mounting screws, please comment. However, the screws are also used and have scratches, and the price will be changed to 5,000 yen including the screws. Shipping will be via Nekopos (mail slot delivery) in a padded envelope. Thank you for viewing.
