I recommend going through your local music store or repair shop first if you can, but you may also order directly from these supplier websites:
JL Smith: Best source for Valentino synthetic products, as well as many other supplies and tools.
MusicMedic.com: Saxophone pads and many other supplies and tools.
Ferree's Tools: General source for pads, supplies, and tools
Local Hobby or Hardware Stores: These can be excellent sources for tiny tools like precision screwdrivers or nut drivers. Look for high quality pliers (like Knipex brand) or small plastic/urethane mallets too!
