A typical music classroom that's filled with instruments, sheet music stands and risers is one crowded place. So, if you're looking for a storage solution for violins, violas and trumpets that will help organize, store, protect and easily move these instruments all at once around your classroom or back and forth to your storage room or stage area, you're in luck. Meet the Band Room Violin & Viola Case Shelf Rack. This two-tiered storage shelf-on-wheels can hold 20+ instruments (may vary depending on case size).
