Each instrument requires its own unique supplies, accessories, and materials. Some of these items (reeds, valve oil, cork grease, slide grease, swabs, drum sticks, etc.) are "consumable" and will need to be replaced from time to time.  Attached below are links to Amazon.com lists for ease of ordering. You can also find these items at our local family-owned music store, Bell's Music Shop. There are different types of reeds, valve oils, swabs, etc., and if you tell the associate at Bell's Music that you are from Wilson M.S., they have a reference list to let you know which specific brands & sizes we recommend for our students.
