This is a small, lightweight music stand rack with external dimensions of 85mm. It can be attached to any brand of folding music stand by turning the knob on the resin holder at the back. Although it has a small storage capacity, it is suitable for players who carry relatively few items during performance, such as flutists, double reed players, and string instrumentalists. (If you want to store larger and heavier items, please refer to Music Stand Rack Type C (S, L).) The edges of the wooden (paulownia, brown) box are rounded, and sponge cushions are attached to the bottom to prevent noise. The holder is also screwed and glued, and a stainless steel compression coil spring has been added for smooth attachment.
