This is a custom-made wooden tray that can be attached to the middle pipe of a music stand using a one-touch resin holder on the back. It's designed to hold small items you want to keep handy while playing, such as a metronome, tuner, mouthpiece, cap, reed case, swab, mute, rosin, picks, capo, pencil, smartphone, and glasses. The bottom of the antique-style tray has a cushion sheet to prevent loud noises during ensemble practice. The external dimensions of the tray are 257mm wide x 97mm deep x 32mm high. The total weight is only 120g, and it can rotate 360 degrees depending on the usage situation. 【Important Notes!】The optimal pipe thickness (outer diameter) is 13mm (e.g., the second tier of Cosmo stands, the first tier of Wittner stands). The second tier of Yamaha stands is 14mm, so the holder may occasionally break. Please use Type A or Type C for Yamaha stands. ※There are three types of music stand racks: A, B, and C, depending on the mounting method. Please choose according to your needs and the manufacturer. ※The music stand and metronome in the photos are not included. ※Please note that there may be knots in the wood, and the color and grain may differ from the photos. ※Specifications are subject to change without notice. ※Featured on NHK "Shuto-ken Joho Netadori" in July 2019. ※If purchased together with an ultra-lightweight, compact music stand, you will receive a 300 yen discount on the total price. Please contact us via "bulk purchase request." ※Please do not ask for a discount. ※Available for immediate purchase.
