Instrument - Rent of buy one from a local music store.
DON'T BUY INSTRUMENTS FROM AMAZON, EBAY, WALMART, COSTCO, ETC - THEY ARE TERRIBLE!
Music stand - to use at home for daily practice. Don't get the cheap, flimsy folding metal music stands - they are garbage. Here are a few suggestions - music stand 1, music stand 2, music stand 3. Your local music store will also have similar options.
Flute care kit: Conn Flute Care Kit or Giardinelli Flute Care Kit. A local music store will have something similar.
Flute Case Cover - Optional, but nice to have. They often have a shoulder strap to make carrying easier and a zipper pocket for storing the cleaning rod and cloth separately from the instrument, which is better for the instrument.
